Is black face okay again now or is that still cultural appropriation?

How do we know how white we are? And how do we know when we're less white?

If I use teeth whitening does that count against my colored credits?

If I use words like "homies" and "brothas" is that good or bad?

Is eatting KFC appropriate? Churches chicken, Popeyes? I don't want to offend anyone.

And what about watermelons. The season is coming up soon. What do I do? I'm terrified.
