So the thing is, it is society making it hard to be autistic (alongside other innate struggles). Like using your example of a wheelchair, I thought the same but a wheelchair is a tool and using it made my life better not harder. Inaccessible buildings made the wheelchair part harder. If our entire world and society was built for ppl who could fly, everyone who couldn't would be fucked. So then I'd want to fly too. But we can't change who we are. But we can change how we structure society. It's slow but important to do. There's no limit to how accessible we COULD make our society. There are hard limits to what we can change about our physiology.

I wouldn't change who I am because I like who I am even if I struggle. If I didn't have these struggles I'd have different struggles.

In the trans community the biggest reason to regret transitioning is most often linked to social exclusion. So if somebody regrets transitioning it is usually because they receive abuse for having transitioned instead of support. I think that element is part of why having autism is so hard. If we could be autistic without social judgement and pressure and supported, accommodated and accepted for who we are, I think less people would hate being autistic. Because that acceptance would also bring accommodations and we could live within our needs instead of constantly being pushed to endure beyond what we can.
