The weirdest thing about this discourse is that people against it somehow seem to be very convinced self diagnosis is exclusively done based on internet memes or something along those lines. I spend years researching, reading multiple books by actual experts, reading scientific publications and hanging out in autism spaces to see if I fit in.
... Almost like somebody who tends to ... Oh idk have a special interest.
And the contra side also dismisses privilege. It's known that autism is under diagnosed in minorities. And things like I'd need to travel 5 hours (one way) multiple times to get a diagnosis. Potentially staying overnight. They'd want to talk to my abusive parents. I'm chronically ill. It's not realistic and I live in a country that has reasonable health care. I wouldn't magically be employable afterwards anyway or have some other tangible benefit. I'd just get somebody in a 15 € white coat tell me what I already know. Or dismiss me because they read me as the wrong gender and yolo autistic people don't have humor.
My exfather deliberately cooked food I didn't like to prove I actually like it and just do it for attention. He's a trained chef. It started when I was three and only stopped when I moved out and stopped eating his meals.
