An Anti-Defamation League gets it wrong about left wing vs. right wing murderers

John Lott at the Crime Prevention Research Center has a new research piece "The Anti-Defamation League’s Absurd Claim that 100% of Domestic Extremist Murders were Committed by “Right-wing Extremists,” most murders were actually committed by people who should be classified as “Left-wing Extremists”

------------------------------------------------
The Anti-Defamation League has a new report titled: “Murder and Extremism in the United States in 2022.” They claim that all the murderers of the 25 people murdered by extremists in 2022 were “right-wingers,” which they describe as white supremacists, anti-government extremists, QAnon extremists, and other right-wing extremists. Their report has been getting extensive uncritical news coverage. In fact, most of these murders were committed by either an environmentalist or a nonbinary “socialist.” Are those the views of “right-wingers”? Our data is available here.
