Well I'm in in way, shape, or form insinuating that all black people walk around saying "nigger' to each other, or that all black people listen to rap music. However the ones that DO constantly say "nigger" to each other out loud and in public are always the first ones ready to start a fight if they hear someone who isn't black say it (even if its a private conversation and it was said quietly). They are basically looking for a fight. I've never heard Mexicans calling each other "wetback", never heard asians call each other "egg rolls" and have never heard white people call each other "crackers or honkeys". I also think that it is totally absurd the way that some black people say "well I didn't say nigger, I said nigga", as if saying the original word in a horribly botched way makes it alright/different somehow.
...one can be sure of nothing until it has already happened...
