Not to needlessly throw around buzzwords but the way that white queer people will try to gaslight you into thinking that it’s okay for them to be racist just because they’re queer is wild.
Having experienced homophobia is not an excuse for racism. Being queer is not an excuse for racism. There is no “I’m also a minority” get out of racist jail free card. If you call me a slur because “you’re just joking”, I’m going to be mean to you. If you put a towel on your head and use AAVE as an ironic joke, I’m going to be mean to you.
I know a lot of younger white people are so chronically online that “ironic homophobia” is now super funny but leave my blackness out of it. There is no level of “minority solidarity” that is going to make it okay for you to be racist. Your queerness is not a shield.
