I do agree that there should be a term for 1. "autismized and disenfranchised alongside the autism category by the medical and education system, especially since childhood", and I can understand why people want a term for 2. "consistently and significantly more than average socially excluded and abused for a perceived weirdness and inability to act 'normally'". the problem is that "autistic", as a word that gets conceptualised as a neurotype and not a fluctuating externally imposed perception + also acts as a term for 3. "recognizes themselves and self identifies with the medically and socially determined 'symptoms' of autism", categorically cannot be that term. many many many people in that third category are not part of the first two, even though they might think they are, and in that context speaking of the "social reality" of autism is a dead-end
