@Qwyrdo I know it does! But I'm limited in my own experience.
I will say that I think it's a good rule because a lot of "subtle" racism comes in the form of more extreme imitations of AAVE and so it's probably easier to have a rule like that than to say "no harmful imitations of other races".

@Maenad I really love hearing my sister speak an idiolect of AAVE.
