I've been through some shit due to my autism, including a period of homelessness and trauma. It's caused me massive amounts of pain over the decades, but... despite needing support to function, I'd still keep it.
I don't think it's necessarily wrong for people to say they are autistic and would stay autistic given the choice. I don't think it's wrong to say the opposite. I get much, much more uncomfortable when that choice is external. If my parents knew I would be autistic, they would have aborted me. I think I've been a force for good in the world even with my trauma. I dunno, that makes me sad to think about.
