I have never seen how bad the word 'retard' is, to be perfectly honest. If someone does something stupid or whatever, I don't think there's a problem with saying, "Ha, you're being a retard!". Now that would be someone who ISN'T really retarded. You know, just playing around, but calling someone who's actually handicapped a retard...not cool. Now I could care less about political correctness, but it's just plain rude in my eyes. As far as I'm concerned, there is a difference between thinking something is unacceptable and not saying what you want to say because society says it's bad.
