If someone called me that in the media (radio, TV, Newspaper,etc), I would be extremely angry. I don't care about the color of the person, it is not funny. I don't care about nappy headed. A man cannot call a woman a wh### in the media and expect her to laugh and just accept it.
Imus cannot hide behind other people who say vulgar and inapporiate things. There has been and always will be people in this society who will disrespect themselves and others. There are also people with class and high standards of all races who are outraged that Imus would go on the radio and call women wh####.
I don't see why it is so justified in your mind, for people to threaten and harrass innocent women for standing up to defend themselves from a character attack by Imus.
