You sure do post a lot of threads about race/racism... Why this fascination? It seems that the preoccupation with race is kind of a negative thing and people should focus on what they have in common instead.
People calling each other niggers doesn't really serve any purpose... I believe some Black people started calling each other that to try to take some of the hurtfulness and negativity out of that word.. and now they have pretty much succeeded and you can hear the word all over music and movies.. so now would be a good time to stop using it for that reason.. or any reason.
