Here's what he said that got him fired for "racism":

A couple of weeks ago, I was watching video of people fighting on the street in Washington. A group of Trump guys surrounded an Antifa kid and started pounding the living shit out of him. It was three against one, at least. Jumping a guy like that is dishonorable obviously. It’s not how white men fight. Yet suddenly I found myself rooting for the mob against the man, hoping they’d hit him harder, kill him. I really wanted them to hurt the kid. I could taste it. Then somewhere deep in my brain, an alarm went off: this isn’t good for me. I’m becoming something I don’t want to be. The Antifa creep is a human being. Much as I despise what he says and does, much as I’m sure I’d hate him personally if I knew him, I shouldn’t gloat over his suffering. I should be bothered by it. I should remember that somewhere somebody probably loves this kid, and would be crushed if he was killed. If I don’t care about those things, if I reduce people to their politics, how am I better than he is?

So I guess even being tempted is enough to make you guilty. Oh wait, as a white man he's automatically a racist anyway.
