The common word everyone uses for someone with a mental disability is retarded. Everyone is at fault here for doing this at least once in their lifetime, but the people that refer to the mentally challenged constantly as retarded are terrible people. My standpoint on this comes from the fact that I have seen some people that are mentally challenged beat normal students in school academics. This is mainly in cases of something like down syndrome, not a very severe mental illness. It isn't right to call these poor people retarded. In fact, the normal humans beings that are complete idiots should be classified as retarded. Basically, someone that doesn't know the capital of their own state, asking how to ask a question on a website and in doing so asking a question on the website, (the next two are my favorites) asking how people got around before they invented google maps, and finally why there were hashtags (POUND SYMBOLS) on old cellphones before twitter was invented. Yea, and the mentally challenged deserve to be classified as retarded compared to people who do this? Guess so.
