I'm quite sure no harm intended by this thread, but pretty soon up came this:

"It doesn't count for retards. Idiots hate retards! I figger we will force all the retards to go to Newfoundland or work at McDonalds flippin burgers, eh, while us idiots live off the fat of the land."

I think we're too close to words like that being used in earnest and to hurt for it to feel too comfortable about using them too freely in play.
