The "N" word

The actor Michel Richards is being hassled by the black community lately because he lost his temper and called two black comedy patrons... niggers. Blacks have started a movement to try to have the word banned entirely from public usage in the arts and media. They say that the word is terrible because it is entirely a "hate word". Here's the deal. I think that if they are successful, there are other words that need to be banned as well. One such word is the "F" word. It's entirely a hate word as well. And there are phraises that are vulgar and hateful too. Why can't they be banned.
