You have the assumption that none of us here are black or live around black culture. Race is only a concept, pretty discredited except for sociologic aspects, pretty much stupid. Personally, I've lived with black culture of several sorts, latino culture (I once was all viva la raza, which passed), white culture, asian culture, none of which are some kind of monolithic thing set in concrete unless you go back to the tribe, and, as it happens, one of my relatives was tribal, so don't lecture me.
You have been taught some kind of set of mores about race that represent caricatures.
The whole idea of doing race caricature cartoons is icky.
Consider cartoons with some other premise.
Move out sometimes and talk with people.
