@Dyrne & @Porpoises I agree. If someone is trying to be respectful & coming from a good place, then it seems counter productive to start screaming at them and or refuse to talk to them, if you want your voice heard.
I think the fact that some people like to be called black and others like to be called POC does clearly cause confusion. Perhaps, if someone shows concern about getting it right, for the benefit of their particular audience, then maybe that particular person/audience they are conversing with could let them know which term they prefer and move on?
Re: the point Porpoises made about the students, I do confess to worrying that this idea of just refusing to speak to people who don't agree with you 100% is prohibiting their own under standing. Much like the feminists v trans debate. But let's not open that can of worms right here.
