JohnnyO, it's part of that double standard of "We can say it but you can't!"....and even that is more like a quadruple standard, because it doesn't go both ways.
Case-in-point:
Spike Lee makes a movie called School Daze and it plays on black-held stereotypes of light skinned (wannabe) and dark-skinned (*******) blacks. The names in parenthesis prior were in the movie. Spike Lee is black, so he can get away with that because of the standard and rule that says "We can say it but you can't!"
Now, rewind to last week and Imus riffing on the game. He noted the darker, tougher, tatted Rutgers team against their softer looking opponents and his producer made reference to the Spike Lee film and and "Wannabees and Jigaboos". I don't know how many interviews, news programs, and talkshows since I have heard Imus accused of using the word *******, and that's not even what he did. He (actually his producer) made reference to someone else in the black communities use of that term.
Then, once that reference was made, then the line was crossed, but Imus was already on the line because he had stepped into the shoes of the black man, using black man references and calling on the examples set by Spike Lee. Once in that mode, he said "Nappy headed hos"...again, names that if he were black there would be no problem.
So, that's the standard, and the reason it is so inequitable, is that there is absolutely no similar rules going in the other direction.
Chris Rock, Dave Chappelle, Eddie Murphy, ...you name it, they all have done some hilarious skits and riffs talking about the differences and oddities of whites (can't dance, stay in a haunted house, can't handle a black woman, talk funny, no butt, etc, etc...).
And as a white man, I find those things hilarious.
Sure...I guess a black person might defend it all by saying that Chris, Dave, and Eddie don't have hate in the heart when they say what they say, or that they are just joking, or that since the white man is on top and the black man on bottom for centuries that it's about time....
....Whatever. It's two different standards, and applying different standards to people BECAUSE of their race IS ABSOLUTELY the ulimate in racism.
