I think there is a big difference between being socially inept or painfully shy and having a true disorder. I think that the level of social incompetence may be pretty high amoung the ADT style fanbois, but I wouldn't throw around autism spectrum disorder lightly because it misses the difference between mental disorder needing treatment and simply shyness needing encouragement and experience. True stalking behavior seems to be much more likely to be Schizophrenic rather than Autistic behavior.

In Pipedream's case, I think that his obvious difficulty with organizing thoughts that is more than just some sort of baseless online flamewar insult goes beyond simple social retardation or shyness. The use of neologisms and repetitive patterns that are recognizable enough for people to mimic focuses that thought disorder more closely towards Autism spectrum vs Schizophreniform disorders. The spontaneous, unsolicited angry responses against posts that discuss relationships seem a bit "odd" at best.

No, this is more than just some baseless internet swordfight accusation/insult.
