Which Side Commits More Political Violence?
Counted by deaths, right-wing attackers are ahead of left-wing ones in every count here over a decade or more. In 2025 the left led in CSIS’s count, by attacks and plots and by deaths. What each count includes, and the filing choices that move it.
Jump to the verdict ↓Mostly the right. Over a decade or more, right-wing attackers have killed more people than left-wing ones in every count on this page that sorts deaths by side, usually several times more. In 2025 the left pulled ahead in CSIS’s count, with 16 attacks and plots to the right’s 10, the first time in more than 30 years, and six deaths to two; in the first half of 2026 the right led again. And if 9/11 is counted, Islamist attackers account for most of the dead.
What each database counts
The figures in this article come from databases that count different things by different rules.
| Database | What it counts | What it leaves out |
|---|---|---|
| FBI hate crime statistics | Crimes police record as motivated by bias; reporting is voluntary, but most agencies do it | Crimes never reported, or not recorded as hate crimes |
| New America | People killed in US terrorist attacks since 9/11, by the attackers’ ideology | 9/11 itself and everything before it |
| CSIS (Center for Strategic and International Studies) | Terrorist attacks and plots since 1994, stopped plots included | Violence without a political aim |
| ADL (Anti-Defamation League) | Killings by people with extremist ties, ideological or not | Injuries |
| ACLED (Armed Conflict Location and Event Data) | Protests, riots and political violence since 2020, from news and other reports | Violence with personal or purely criminal motives |
New America, CSIS, ADL, the Government Accountability Office (GAO) and the Cato Institute all count Islamist or jihadist attacks as a category of their own. Their far right means white supremacist, anti-government and anti-abortion violence; their far left, anarchist, communist, animal-rights and environmental violence. Two filings differ. New America counts “ideological misogyny” and Black separatist or nationalist attacks separately, while CSIS and Cato put misogynist and incel attacks on the right and CSIS puts Black nationalist attacks on the left. Researchers at George Washington University’s Program on Extremism call jihadists “extreme right-wing actors”, but no database here files them on the right, and neither does this article, which uses the databases’ own categories.
The September 11 attacks killed 2,977 people in one day, about 21 times the 142 that New America counts killed by far-right attackers in the years since. Counted in, 9/11 swamps everything else. New America’s count starts after it, and the Cato Institute gives its totals both with and without it.
The far right
Since 9/11, far-right attackers have killed the most people in most of these counts, narrowly in New America’s, while GAO’s count to 2016 goes the other way.
How to read it: each bar is the number of people killed in the United States since 9/11, to July 2026, by attackers of one ideology, in New America’s categories and labels; 9/11’s own 2,977 dead are not counted. The second bar is 142 plus 17, on the Cato Institute’s filing of misogynist and incel attacks. Source: New America, Terrorism in America After 9/11.
| Category | People killed |
|---|---|
| Far right | 142 |
| Far right plus ideological misogyny (Cato’s filing) | 159 |
| Jihadists | 122 |
| Ideological misogyny | 17 |
| Black separatist/nationalist | 13 |
| Far left | 3 |
ADL counted 47 to 79 killings by extremists a year in 2015 to 2019 and 13 in 2024, the third fall in a row; it recorded no extremist-related mass shooting that year. Every killing it counted in 2022, 2023 and 2024 was by right-wing extremists.
| Attack | Year | Attacker and motive | Deaths |
|---|---|---|---|
| Oklahoma City bombing | 1995 | Timothy McVeigh, anti-government | 168 |
| Oak Creek Sikh temple | 2012 | Wade Michael Page, neo-Nazi | 7 |
| Charleston church | 2015 | Dylann Roof, white supremacist, targeting Black worshippers | 9 |
| Pittsburgh synagogue | 2018 | Robert Bowers, antisemitic | 11 |
| El Paso Walmart | 2019 | Patrick Crusius, anti-Hispanic white nationalist | 23 |
| Buffalo supermarket | 2022 | Payton Gendron, white supremacist, targeting Black shoppers | 10 |
The far left
Far-left attackers have killed fewer people in the United States since 9/11 than far-right or jihadist ones; New America counts three far-left deaths in that time. CSIS, a Washington think tank that also counts foiled plots and files Black nationalism under the left, shows how much the span of years matters.
How to read them: the first chart counts attacks and plots from 2016 to 4 July 2025; the second, the people killed by each side’s attacks over the past decade to that date. Red is right-wing, green left-wing.
| Measure | Right-wing | Left-wing |
|---|---|---|
| Attacks and plots, 2016 to 4 July 2025 | 152 | 41 |
| People killed, past decade to July 2025 | 112 | 13 |
Source: CSIS’s brief of 25 September 2025; the 152 is Axios’s count from CSIS’s data. Jihadist attacks killed 82 over the decade; the brief’s text gives no matching count of their attacks and plots.
In 2025 CSIS counted 16 left-wing attacks and plots against 10 right-wing, which it called the first time in more than 30 years the left was ahead. Left-wing attacks killed six people that year, Charlie Kirk among them, and right-wing attacks two. CSIS cautions that the gap rests on small counts, and in the first half of 2026 the right led again, five attacks and plots to one.
ACLED counts a demonstration as violent when demonstrators clash, loot, block roads or damage property, even if police started it. In Minneapolis and Saint Paul alone, owners and insurance experts estimated the damage could top $500 million, the Star Tribune reported in June 2020. CSIS says most protests, looting and unrest are not terrorism, because some are not violent and others lack a political motive; it did count attacks such as the burning of Minneapolis’s Third Precinct police station.
In the past decade 20 of CSIS’s 35 left-wing attacks used arson or incendiaries; CSIS left out the 2025 attacks on Teslas as vandalism. Ten of the 13 people killed by left-wing attacks over the decade were police officers shot in ambushes.
Religious violence
New America files attacks by the attacker’s cause, and counts deaths caused by jihadists. Charles Kurzman of the University of North Carolina counts Muslim Americans involved in violent extremism, a rule set by who the attacker is as well as what they did.
The databases put violence against abortion providers on the right. New America counts anti-abortion violence as far-right terrorism, and CSIS counts opposition to abortion as a right-wing motive. As with New America’s jihadist count, the count follows the attacker’s cause, not their religion.
The National Abortion Federation is the professional association of abortion providers, and these are its own totals.
Eric Rudolph, who pleaded guilty in 2005, bombed the 1996 Atlanta Olympics, two clinics that performed abortions and a gay nightclub, killing a spectator and a police officer. His statement blamed legal abortion, and he had claimed two of the Atlanta bombings in letters signed “Army of God”, the name of an underground anti-abortion group. Scott Roeder shot Dr. George Tiller dead in Tiller’s Wichita church in 2009 to stop him performing abortions, and testified that his conversion to Christianity had led him to oppose abortion.
Jewish extremist violenceThe FBI suspected members of the Jewish Defense League of a series of bombings in 1985, including the one that killed Alex Odeh, an Arab-American civil rights organizer, at his office in Santa Ana; no one has been convicted. In 2001 the group’s leader, Irv Rubin, and Earl Krugel were arrested for plotting to bomb a mosque in Culver City and a congressman’s office; Krugel pleaded guilty.
Hate crime counts record the target
Hate crime statistics measure something different. The FBI counts an offense as a hate crime when police find it was motivated by bias against race, ethnicity, religion, disability, sexual orientation, gender or gender identity. Politics is not one of those categories, so the count records who was targeted and says nothing about which side the attacker was on.
The count is also a floor. Not every agency reports: 16,791 took part in 2025, covering 95.3% of the population. The Bureau of Justice Statistics’ victim survey, which counts crimes whether or not anyone told the police, found about 246,900 hate crime victimizations a year from 2005 to 2019. The FBI recorded 7,314 hate crime incidents in 2019.
How to read it: each bar is the number of hate crime incidents reported to the FBI in 2025 with that single bias; taller means more incidents reported, not necessarily more committed.
| Bias | Incidents |
|---|---|
| Race, ethnicity or ancestry | 5,859 |
| Religion | 2,408 |
| Sexual orientation | 1,527 |
| Gender identity | 489 |
| Disability | 145 |
| Gender | 100 |
Source: FBI hate crime statistics for 2025, as compiled from the FBI Crime Data Explorer by the Arab American Institute (table updated 17 August 2026). The six rows sum to 10,528; another 353 incidents had more than one bias, making 10,881 in all. The total fell about 7% from 2024 and, by the Institute’s count, is the lowest in five years, while anti-Latino incidents rose to 1,002, the most ever recorded for that category.
Anti-Jewish incidents show why the target does not settle the side. In the Institute’s compilation they were 1,528 of the 2,408 religion-based incidents in 2025, 63%. The Poway synagogue gunman in 2019 was a white supremacist who wanted to kill Jews and Muslims. The two who attacked a kosher market in Jersey City the same year had shown interest in the Black Hebrew Israelites, and New Jersey’s attorney general said they hated Jews and the police. A count by target puts both attacks under anti-Jewish bias.
The last few years against the long run
The Cato Institute counts people murdered in politically motivated attacks on US soil since 1975. Its September 2025 count, published the day after the killing of Charlie Kirk and covering 1 January 1975 to 10 September 2025, put right-wing attackers at 391 deaths and left-wing attackers at 65; with 9/11 set aside, that is 63% of deaths against 10%. Only 79 of its 3,597 deaths came from 2020 on, about 0.07% of all murders in those years. Of those 79, over half were attributed to right-wing attackers, 22% to left-wing and 21% to Islamist ones.
Cato’s fuller 2026 analysis, to the end of 2025, puts the totals at 363 right-wing and 68 left-wing. Once 9/11 and Oklahoma City are set aside, the remaining 430 murders split 45% right-wing, 32% Islamist and 16% left-wing, and its test finds no statistically significant rise in deadly attacks over the 51 years.
So once 9/11 is set aside, the right-wing share is the largest in each of these counts, and the left-wing share since 2020 is about twice the 10% it had over the whole period. Cato warns that the numbers are so small that a single attack could reverse the shares; split into 17 three-year periods outside 9/11 and Oklahoma City, its count has left-wing attackers the deadliest in three. CSIS’s count of attacks and plots shows the same shift, with left-wing ones outnumbering right-wing ones in 2025 for the first time in more than 30 years, from a very low base.
| Figures | Misread on the right | Misread on the left |
|---|---|---|
| Far-right killings | Treating the counts of right-wing killings as biased wholesale, instead of disputing particular cases | Quoting the far-right share of deaths without saying 9/11 is left out; with it counted, Islamist attackers account for 87% of deaths in Cato’s count |
| Far-left violence | Calling the Insurance Information Institute’s estimate of $1 billion to $2 billion in claims from two weeks of unrest in 2020 damage done by BLM or antifa; the estimate attributes it to no one | “93% of BLM protests were peaceful”, used to wave away the violent minority and the damage it did |
| Islamist violence | Counting 9/11 in a long-run total as if attacks on that scale recur; citing Islamist deaths abroad as evidence about American Muslims | Treating Kurzman’s count, 0.04% of all murders, as proof that there is no risk of a mass-casualty attack by foreign networks |
The verdict: what the evidence shows
Counted by deaths, the answer is the right, and not narrowly. Over the decade to July 2025, CSIS counts 112 people killed in right-wing attacks and 13 in left-wing ones. Across 1975 to 2025, the Cato Institute puts 10% of the deaths from political attacks on right-wing attackers and 2% on left-wing ones, and 45% against 16% once 9/11 and Oklahoma City are set aside. Every count on this page that sorts deaths by side over a decade or more puts the right ahead of the left.
In 2025 the pattern broke. CSIS recorded 16 left-wing attacks and plots against 10 right-wing, the first time in more than 30 years that the left was ahead, as right-wing incidents fell and left-wing ones rose from a low base. Left-wing attacks killed six people that year and right-wing ones two. It is a real change, on small numbers, and it has not lasted so far; in the first half of 2026 CSIS counts five right-wing attacks and plots against one left-wing. Two filing choices move the totals without changing the order between left and right: where incel attacks go, and whether 9/11 is counted. Counted in, 9/11 makes Islamist attackers the deadliest of all, with 87% of the deaths in Cato’s count since 1975.
This article concludes that: (1) right-wing attackers have killed more people in the United States than left-wing ones in every count here that sorts deaths by side over a decade or more; (2) in 2025 left-wing attacks and plots outnumbered right-wing ones, the first time in more than 30 years, and left-wing attacks killed more people, on small numbers; (3) counting 9/11 makes Islamist attackers the deadliest without changing the order between left and right.
These conclusions would be falsified by:
• A count of deaths over a decade or more in which left-wing attackers killed more people than right-wing ones
• Counts for later years showing left-wing attacks and plots, and deaths, back ahead of right-wing ones and staying there, which would make 2025 the start of a trend
• A refiling of disputed cases large enough to close the gaps in deaths, since the counts do not always file the same attack the same way
