How does one deal with ideas like those stated, or implicit, in the above?
"Black culture" is something separate from "white culture"? The poster says "the white man used...", in an apparent reference to...what, exactly? White culture? White society? Everybody he doesn't like?
"Black culture spoke back... 'we' are going to use it how we see fit in 'our' society" Separate society?
Ranting about "a white man."
IMHO, you cannot have separate behavioral rules for "black culture' and for "the white man," unless your intent is to define and preserve separate - enforcedly separate - population groups. If you choose to do that, you guarantee inequality, because "separate but equal" simply does not happen. Power does not work that way.
I have to say, I find the argument about the n-word -- the argument that it's fine for some people to utter it, but offensive for others to utter it, with the distinction based essentially entirely on the melanin content of the speaker's skin -- to be deeply offensive...racist...and frankly, really stupid.
