What's wrong is the intolerance of the media then or those who would punch someone in the face over the use of a word. Words do not make someone a racist, the intent behind it and most importantly actions do. Without direct knowledge of either, nobody has just cause to destroy someone through the use of media or through bodily harm.
What is even more absurd is the notion that partitioning the use of words by skin color does anything other then drive wedges between the races.
Perhaps Riley Cooper used the words he did not because he is a racist but because his closest friends on the team are black and they use a word like n****a interchangeably with words like Mutha****. To them just another salty word to use when you are expressing yourself in anger.
Of course if a black teammate had said I want to fight every n****" at that concert that is ok because somehow the color of the skin wrapped around the mouth that utters it determines whether or not someone is a racist.
Years ago I went to see the Chili Peppers in concert in Charlotte. Snoop Dog opened for them and I was subjected to flurry of racist rants with n****a used just about every other word. Why should I, and every other person in that audience be subjected to a word that is supposedly so bad that it justifies public humiliation, loss of employment and physical harm?
Why of course because the fella saying it is a black man, who can not only say it in private to other black folks but use it as a blunt instrument to openly assault white people and remind them that a very long time ago black people were slaves in this country.
At some point the black community is going to have to either discontinue using it or give up exclusivity to it.
