I once had a coworker fucking uno reverso card me when he started talking some weird white Islamo-nationalist shit and then went onto some really racist tirade against black folk.
He kept talking about the need to defend ones' own people, so I brought up the Black Panthers and what they stood for, what they did in service to not only black people but for the people entirely. I told him they protected their own and that our state killed them for it.
He brought up Hitler. He said "just like Hitler, he was protecting his own"!
I don't even remember what I said after that, I was flabbergasted and almost certain we were both wasted.
