As I've said before, you can tell that it's a psychological thing by how mad some people get when you DARE to suggest that maybe people should reconsider the use of the word. It's one thing to use a word, it's another to use a word with that history and then get indignant when people have an issue with it. They won't have any other word in their vocabulary that they feel that protective of, and the fact that its' a slur meant to dehumanize black people is pretty sad. A lot of these types will get mad when white people sing along to their favorite rap song (as if it's not the fault of rappers using the word in songs they KNOW will be listened to by all kinds of people), but then disrespect black people who don't want it used around them. And again, no other group uses a slur in such a widespread manner and then allows other groups to do so. In NYC, Asians, Latinos use it but just let a black person call them "my ch*nk" or "my sp*c" and see what happens.
