That makes a lot of sense. When I was younger and didn't know much about ASD's, I read about "classical" (that is, low-functioning) autism quite a bit (back then, no other "spectrum disorders" were even mentioned). I never once thought that people with LFA were less intelligent than anyone else--just that, for some reason, the world didn't make sense to them because they didn't sense things like everyone else did.
I also thought that if telepathy were possible, communication with someone who couldn't speak might actually reveal that they were NOT "ret*d" at all. I still believe that.
