None, but I do think this is a little bit of old people trying to hold on to what was. The fact of the matter is that words and language as a whole change over time. Many of us of a certain age know what the N word means and think about it a certain way. A lot of younger people think differently. To them Nigga and Nigger are literally two different things. This whole "nonblack people using the N word" thing is only going to get more prominent generation by generation. You can't really blame younger people for that. You have to blame our generation for putting that shit out into the public space as pervasively as we did. If we didn't want nonblacks saying the word, we shouldn't have been selling it to them.
