White people have been bringing down black people for centuries and using the N word. They've been compared to apes and porchmonkey's with that term. The same can't be said about any word that describes a white person. Of course I think it only matters what context the word is used in, like saying it in a rap song or w/e is ok in my opinion (even though I'm not black and it's only my opinion) but saying it as an insult to someone is a different story.
Saying the history and context of a word not being important is ignorant.
So Sex and the f word can be used interchangeably since they mean the same thing?
By centuries you probably mean a couple hundred years dominance that ran counter to the previous 6800, when black, white, yellow, red, orange, tan, olive, and brown all enslaved each other and kept green martians happy by building pyramids and other really cool phallic displays.
