Alright, since political correctness is being such a big hangup in this discussion, let me explain something: "ret*d" really is a nice name for the condition. There are more slurs against people with various mental disabilities than slurs for Asians, who seem to have the second most slurs attruibuted to them. While it is possible to call the ret*d "ret*ds", " 'tards", "tardmonkeys", "idiots", "morons", "imbiciles", "mongoloids", or "waterheads", the word "ret*d" is reasonably nice and straightforward compared to most terms society has been known to use.
