When blacks say it to each other, it is not derogatory. Not all black people use this term, you cannot judge all blacks by lyrics in rap music.
I don't know the details about Paula Deen but I do not think she is a racist. I could be wrong
So you are saying it is alright for one black to call another black a n----r, but not okay for a white to call a black a n----r? Bit of a double standard?
