As an autistic adult, it's frustrating to me that high-functioning autistics and parents/caregivers of low-functioning autistics never seem to realize that the other kind exists. You wind up with people insisting that perfectly functional human beings need to be cured, which those same human beings insist that there's nothing wrong with a kid who can't speak or dress himself at age 10.
Merging Asperger's into Autism was the natural result of finally evaluating all of his research. This shows that he always worked with persons who are at all parts of the spectrum, including the worst cases people think about when they hear autism. Historical circumstances led to him being very popular for the "light" cases (i.e. the cases which didn't lead to immediate termination of life under the Third Reich), but the body of his research shows that he always was aware of the full nature of it. Unlike people who split it in autism, high-functioning autism, Asperger and whatever "separate" things they found.
It's incredibly insulting, actually.
Autism is at best as much fun as being born with arthritis.
...for some but not all autistic people.
I'd say that this is no different for neurotypical people. If you find a good place where you can work and someone can pay you for it, and you can furnish your life in such a way that it doesn't clash with you, then you will be happy. Your premise that it compares at all to something that gives someone constant low-key pain is spurious and does a disservice to the fine human beings it refers to.
I'm talking about getting blindsided by some bad noise or light or thing moving wrong, and having to leave right in the middle of something.
I'm talking about remembering to actively suppress your urge to rock or fidget, because otherwise people will start treating you like you're nuts.
I'm talking about not knowing that people are pissed off at you, for weeks, even years, even though everyone around you knows it, but won't say anything because you're expected to know.
I'm talking about not being able to look in someone's eyes, but knowing you're expected to, and some days it's especially hard.
I'm talking about the room suddenly becoming silent, again, and you're left wondering what you fucked up this time.
I'm talking about relationships slowly going off the rails because you can't seem to express yourself properly, and the other person, though trying to be understanding, is losing patience.
Like arthritis, it creeps and moves, and some things are painful one day, not painful the next. But it's ever present, and catches you unaware.
