People didn't seem to take his question to seriously, but I think it's a pretty good question. I asked a couple of my friends this awhile back and didn't get a serious answer out of them either.
For the most part, a lot of minorities tend to be pretty damn sensitive, and get offended really easily. I know a lot of people who before they really get to know me feel as if they have to walk on eggshells around me as far as jokes that are okay to tell or trying to find the "okay" terms to use around me.
However, people say "white boy" all the damn time. I hear it all the time, "Aye, white boy" "Who's the white boy" etc. And I think it's offensive. I can't say that I haven't used the term before at one time or another. However, when you really stop and think about it, it is and should be considered offensive I think.
I know if someone came up to me, like "Hey Black Girl" that wouldn't fly over well with me. But for some reason a lot of people seem real lax about it, like "I don't care" "I've always been called that" etc. That doesn't make it okay though. Yeah, I know it's a double standard, but that doesn't mean that if it offends you, you have to accept it.
