People shouldn't call actual retarded people retarded. That is not politically correct. People have to call them developmentally challenged. People who are called retarded now are people who act stupid. A lot of liberal minded people get pissed off if you call someone retarded. Save your self the trouble and never say the word retarded ever. So you don't have to deal with idiots getting on your ass about not being "politically correct". Take the high road because most liberal minded people are not capable of taking the high road.
