I find it quite annoying that we can't say "retarded" anymore but "autistic" and "autism" are valid insults. This has a lot to do with high-profile autistic people such as Christian Weston Chandler, who have a whole host of other psychological and emotional damage that has little to do with autism itself. They are the ones who wear their condition on their sleeve and try to use it to excuse all sorts of reprehensible behavior. Until in the public mind the words "autism" and "Asperger's" become associated with cringe.
