First, for just this one incident, I don't think Imus should have been fired.
Second, this wasn't just one incident. Imus was a disgrace; this was just the tipping point.
Third, I've looked at the photos of the game, of the team, and I've seen absolutely no way that the comment was justified. I didn't spot any tattoos that they claimed the Rutger's team had. They obviously were not out on the court with long nails, extreme cleavage, tight clothes, dreds, Afros, corn rows, excessive jewelry. One player had braids; most had their hair pulled back.
If they had appeared "whorish" or did all have braids, corn rows, Afros, dreds, I'd be defending Imus. I have heard literally dozens of Black people complaining about younger peoples hairstyle and how they wear clothing; I'm the guy usually defending them. None of them would look at that group of ladies, in that situation, and say that they were "nappy headed" nor "hos." I would not either.
Fourth, in terms of apologies, in a simultaneous situation, I heard a radio commentator calling of Revs. Jackson and Sharpton to apologize to the Duke students wrongly accused of rape. I agree with that commentator; her name is Whoopi Goldberg.
