What does that have to do with anything?
Saying nigger does not make you one. Calling black people niggers is a good indicator of you being one, but simply using the word, especially when just using it in the context of what other people are saying, has nothing to do with your political leaning, or view of black people.
A word is more than the dictionary definition behind it. A word is also shaped by the intent, context, and other words used alongside it.
