I saw a study the WaPo referenced last year claiming right wingers killed more than Muslims (if you set the parameters just right). I looked up every one of them and one was a gang of cop-killers, 3 white guys and 2 black guys. How they got chalked up as White Supremacists, I don’t know.
The press would call a gang of one mulatto and ten black guys a gang of white supremacists.
