I think he probably didn't mean to offend, and yes, he used a phrase that black people use amoung themselves, i'm sure. BUT...
if MY daughter was on a college sports team, and working her butt off and doing really well, and someone referred to her as a "ho" or a 'country hick bitch', or any other derogatory way, i'd be FURIOUS.
i think what imus did so wrong was that he called these young women specifically a name. nomatter what that word was, whether it was 'ho' or 'bitch' or 'nappy head'- it wasn't a general name calling- it was specific, and it was directed at young, hard working, successful girls who in no way were asking for it.
