Actually I have. I have never understood why white people are prohibited from using the same terminology as what blacks themselves use in their own institutions such as The United Negro College Fund, The National Assoc. for the Advancement of Colored People, and The Congressional Black Caucus. Could you even imagine calling a black person a "Hey panther!" LOL
Pfft, whatever. I say "black" and that's just too bad for anyone who doesn't like it.
Because the goal is control among certain race baiting associations as in "I'LL tell you what you can say and what you can't say."
