Last week, The New York Times featured an illustrated timeline of “white extremist” killings over the last nine years. According to the Times, the record shows “an informal global network of white extremists whose violent attacks are occurring with greater frequency in the West.”

The idea that white supremacist violence is a growing global threat has gained more currency recently, notably in the wake of the ghastly Christchurch mosque massacre. New York Rep. Alexandria Ocasio-Cortez, for instance, asserted that “White supremacists committed the largest # of extremist killings in 2017.”

No one will deny that people who kill in the name of white supremacy commit evil, but is it true that white extremists are sowing a growing amount of worldwide mayhem? The evidence suggests otherwise.

Even a superficial glance at the record indicates that of the nearly 20,000 people killed in thousands of extremist killings in 2017, white supremacists were responsible for very few.

The worst terrorist event of 2017, according to the State Department, was the explosion of a truck bomb in Somalia, which killed more than 580 people. This act is believed to have been the work of Al-Shabaab, which was responsible for 97 percent of the 370 instances of extremist killings in Somalia in 2017, accounting for about 1,400 deaths.

The deadliest extremist attack in Egypt’s history took place in 2017, when ISIS-Sinai terrorists converged on a mosque and slaughtered 312 people when they came outside.

White nationalists committed none of the above violent acts, and that’s nothing remarkable: Almost all the world’s extremist violence is concentrated in a handful of regions, where very few white people live. In areas where whites do live (America, Canada, Europe and Australia/New Zealand), white nationalists do indeed perpetrate a significant proportion of the relatively uncommon acts of extremist violence.

Again, this is unsurprising, because whites make up the overwhelming majority of the population there.

The New York Times timeline of “white extremist” murders covers nine years and 15 incidents, bookended by the heinous and indisputably racist attacks in Norway (in 2011) and Christchurch. Some of the most prominent killings among the remaining 13 incidents, though, resist categorization as acts of white racial terror.

Ali Sonboly, the son of Iranian Shiite Muslim immigrants and visibly a racial minority, carried out the 2016 Munich mall shooting. The 2016 Umpqua Community College shooting was carried out by a self-identified “mixed-race” man, as was the 2014 Isla Vista massacre, whose perpetrator believed that being half-Chinese made him unattractive to women.

The 2018 Toronto van massacre was perpetrated by a white man who declared that he was part of an “Incel Rebellion” against the “Chads and Stacys” of the world — in other words, he was angry that he could not get a girlfriend and was committed to overthrowing the “beautiful people.” The Times’ inclusion of these four incidents calls into question the value of its diagnosis of “white extremist killers.”

When Ocasio-Cortez tweeted that white supremacists were responsible for the most extremist killings of 2017, she was obviously wrong (if she meant worldwide, which is unclear from her tweet). There were at least 8,500 such incidents worldwide that year, and white supremacists accounted for perhaps 15 or 20 of them, depending how you count.

Perhaps Ocasio-Cortez was thinking of the US and relying on an Anti-Defamation League report, “Murder and Extremism in the United States in 2017.” According to the ADL, 34 people were killed as a result of extremist violence that year in the United States, eight of them by Sayfullo Saipov on Halloween in lower Manhattan. Another victim was Heather Heyer, who was run over by James Fields during the Charlottesville protests.

Heyer’s killing can legitimately be labeled an act of white-nationalist violence, as Fields was an open admirer of Hitler and the Confederacy. But the other murders that the ADL counts as “extremist-related” are fuzzy, even by the ADL’s standards.

For instance, Frank Ancona, a Klan member from Missouri, was killed in a domestic dispute by his wife, also a Klan member.

The Wall Street Journal, citing the US Extremist Crime Database, reports that the frequency of violent hate crime in the United States has been about the same for 50 years.

White supremacy is insane and immoral, and it may be a significant threat. But it doesn’t account for anywhere near the preponderance of global extremist violence, though one might get a different impression from recent coverage.
