Fire Imus?

As I'm sure you've heard by now, Mr. Imus, a radio host, called some African American females (to be poltically correct) "nappy-headed hos." And he was fired for it. This is huge. It's all over Google, the news, talk shows...
Why? Why was he fired? He apologized.
Because he's white.
Because blacks can refer to other blacks as the n-word, ho, or the b-word. Have you listened to mainstream hip-hop songs lately? Allow me to enlighten you on some of the things BLACK rappers say in songs...
"...That hoe fine but this hoe killer
She leakin, she's soakin' wet...
Shake it like a salt shaker...
Pussy poppin, till you percolate
First booty on duty no time to wait
Make it work, with your wet t-shirt
Bitch you gotta shake it till ya calf muscles hurt..." (Ying Yang Twins)

"I've got hoes (I've got hoes)
In different area codes (area) area codes (codes)
Hoes (hoes..hoes) in different area codes (area) area codes (codes)" (Ludacris)

So why is it that male black rappers are allowed to call women hos but white men aren't? The lyrics in the first song talk about how much this guy wants to have sex with a girl. And we have scandals, like the one with the Notre Dame lacrosse team. Women advertise themselves as nothing more than a vessel of sex. Then they get angry when men take advantage of them.
But I digress...
The point is: Are we one or two Americas? Why do we live by a double standard? Why is it okay for a black man to call another black man the n-word, and for a black man in a song to call a woman a ho or the b-word?
This is unbelievable, how our society allows special intrest groups to be treated so carefully, while we use reverse discrimination to fire a white male for a comment that was supposed to be funny!
I think the lyrics speak for themselves. You decide what you think, and act on it.
