I noticed the same, it's almost as if people are getting diagnosed with autism because they're too awake/too hard to brainwash, so by attaching the "autist" label on them normalfags will be less likely to take them seriously.
Of course I don't mean to say that every autist is smart, there are very smart and very dumb ones out there, and in rare cases there are the average intelligence ones too, the point is rather that they're just throwing all of them under the same label.
For some reason schizo's and autists (not so much with asperger's) seem more human. Either I am deluded or normalfags have become more insane in less than a decade.
