sure its a joke.

Wasn't it TEd who said, all jokes have hurt as a basis?
(except of course, pun!)

Imas made hurtful remarks. they were so hurtful, no one could see the humor.

he pandered to the stereotype of 'beauty' (ie light skin, fair, smooth hair, dainty (ie, not athetic)--oh and let's not forget, 'proper' (ie pure--the classic madonna vs harlot dicotomy of women)

his remarks were sexist and racist. and to some degree he got in trouble for saying them because he is white--some words are racist when used by whites (to talk about blacks) but not when used by blacks to talk about other blacks!

rappers use the word 'ho' to describe women all the time--

but that's OK, but it's not OK for white men to call black women ho's (it's tolerated if they are talking about white women)

it's politicalization of language.

it's been around.
boy (ok term for a child under ten, wrong if used to describe a adult man, racist if used to describe a black over the age of 10)

Young lady (ok for girl (preteen) demeaning, for a teen, insulting and sexist used by a man to an adult woman)

words, have meanings--varieties of meanings.

Nappy haired is not a compliment-- the well established western standard of beauty is for smooth hair--that could be described at racist, but its hard to tell (cleopatra used clay to smooth and straighten her hair.. if straight smooth hair is a 'beauty' feature, it is one that predates european standards of beauty!--curly hair (curly to the point of being nappy) has rarely been considered a beauty feature (in us fair shinned and hair folks, its called "lamb wool' hair, and not considerered a blessing either!)
(a sure sign is clowns and other charactures often have curly, curly hair)
he used a lot of words with negative meanings to describe young women who did nothing but excell. it was mean spirited, and rude.
(but then like the AsP, i don't listen to this 'shock jockey' and my radio listening is pretty much QXR (classic music) and NPR.
