Is everyone in this thread autistic?
If you're referring to Asperger's Syndrome, then in a way, you might say that; however, you must first assume Asperger's is a real condition, which just happens to have the same traits as a specific personality type. I've seen actual autistic people who have an actual disability, and "high-functioning autism" is not autism at all.
So it depends on how you're looking at it, whether or not you believe Asperger's is even a thing. AFAIK the only confirmed autistic member here is kokjo, but most everyone else is just of the INTP/INTJ sort.
