You almost convinced me that since everyone else does it, it logically means that it can't possibly affect anyone.
Funny, though, that made me think of something. There was a word like that that started quite some time ago, and it's still used today. It's used in pop songs, and everything, like the "faggot" example. Plus, it's highly inflaming towards the people it was originally used to describe, before it's meaning started getting permutated, again -- just like the "faggot" example. I wish I could remember what it was.
It begins with a "n", I think. Well, anyway, thank goodness that word doesn't offend anyone either!
