I've gotta say it:
*let's not go there*. Possibly the worst word in the english language, due to its usage. I'm not a PC person generally, but this is the most ignorant and offensive word I can think of, no matter who spews it forth.
And, being white, I usually hear it in this sentance
"I'm not racist, but there are Niggers and there are black people".
Okay, yes, that sentance makes you racist. There is trash in every race, creed, color and religion.
I used to think that was bad, but now I think the worst word I could ever be called would be "victim".
Also, I really and truly detest when someone pronounces the "w" in "sword".
