Um. Long story short he kept saying things like cracker, buckra, I know why all the hatians murdered you people. I was just trying to interact. He said black people knew stuff from birth that white leftists argue their whole life over. Being genuinely curious, I asked what that was, then he started attacking me for being white again so I linked Combat Liberalism where it says not to engage in personal attacks instead of engaging people and said he was being a liberal so blocked me.
IMO he is closer to a black nationalist than a communist, and I totally have critical support for black nationalists hating whites, but it's not a communist position to me. It is what it is.
