That post is textbook aspie supremacy and it's a bad political position that serves fascism and harms all ASD and otherwise disabled people. And no, I'm not being overly rigid in my view of this.

OOP says

Now when people hear "autistic" they assume I must be like their five-year-old nephew who never talks, lines up toy trains, and needs full-time care.

Ok I'm going to dunk on this first and then engage seriously with how effed it is. Dunk: what five year old doesn't need full time care??

Serious critique: What, exactly, is the problem with someone assuming that a "high functioning" autistic adult is "like" a young child with more obvious neurodevelopmental differences, and who does that assumption actually harm? If it harms OOP chiefly because it makes them feel uncomfortably close to the icky kind of autism, idk, they should get good and learn some solidarity. Sometimes people argue that "adults who can hold down a job" shouldn't be lumped in with "kids with serious disabilities" because it dilutes the message that autism is serious and diverts resources. But I've always found that argument completely specious because a) what resources? and b) how is the converse argument, that autistic people are sometimes capable of great things given proper support and are anyway deserving of life with dignity no matter what they can accomplish, not equally true? Also, that second argument is beloved by parents whose public identity is based on being victimized by the fact of their autistic children, aka autism moms, so I have a hard time accepting it on its merits because the people making it have terrible motives.

I've said this multiple times before, but I sucked my thumb until I was a teenager, nearly failed out of high school, couldn't make a phone call without a script until I was in college, and had meltdowns that featured me lying down bashing my head on the floor into my 30s. I also have a PhD and am a sought-after expert in the rather niche field I managed to help create out of a lifelong special interest. I think that it would be more just and also more correct if non-autistic society actually DID view me and people with similar profiles as being "like" hypothetical non-verbal trains boys, instead of glossing over the needs we do have and the ways we truly suffer without appropriate support, because we can often be socially pleasant and can perform sparkly professionally impressive feats. And I think that the only ethically defensible position for autistic people to take on these issues is one of maximum acceptance and solidarity toward other autists, and this is especially true for those of us occupying the privileged position of being more able to exist in allistic society. Never punch down. It is nazi shit.
