So Andy Dick made a joke using the "n" word and had to apologize. He apparently used it to make a point about Michael Richards's blow-up, and there's more apologies going around.
I think the "n" word is offensive, and I don't think anyone should use it. But there's something very bizarre about the logic. If the "n" word is offensive uttered by anyone that wouldn't be the target of it, why is it ok to use it if you're the target? Why should the word mean something completely different depending on the skin color of the person who is using it?
I guess the answer is that the person who could be characterized that way has experienced the bigotry that goes along with the use of the word from the other side, so to speak, but so what? Either a word has a negative connotation or it doesn't. I think it does.
