Interesting, I assume you mean the debate on it's usage in general. I don't think people really mean the true meaning of the word when saying "oh you or that is retarded". I don't see why people get upset when it's used mainly because of this reason, however if you are talking to someone with a disability and then choose to say "you are retarded"...that is when it's a problem. Plus who gets to decide who can or can't use specific words? Freedom of speech people!
