Yeah but those are all lay person vernacular insults. Now we have a scientifically shaped cudgel with which to institutionally beat the weird, troubled, socially awkward and nerdy. All the while claiming to be helping them with their "disability".
It sounds like you are saying an autism diagnosis does not help people, and also possibly that people who are not "actually autistic" are being labeled that way when they are actually socially awkward/nerdy/??. I don't actually know how being labeled autistic is hurting people... I see a few people who it really helps and many whose results seem unaffected by the label, for better or worse.
Source: colleagues on the spectrum (1 good result, 1 getting by, others no + or -), and a friend's child on the spectrum has absolutely, unquestionably benefitted.
I'm going to infer you have some anecdote about this... it's the semi-anonymous internet maybe it would be productive to share it so people see the other side.
