What I often see ignored in these discussions is the idea that a) suffering is a part of life and b) as autism is a spectrum, it's also true that not everyone with autism is actually struggling on a daily basis.
My DH has autism. He has a great career which he loves. There are a lot of people in his industry as a whole and in his workplace specifically who have similar traits to him (no idea if people are diagnosed - that's not the point - it's that he's in a "birds of a feather flock together situation where they gel and in other social situations would likely experience difficulties - my DH does). He's made a life for himself, before he had any idea of the diagnosis, which feels comfortable to him. About twice a year when he has to do large, company-wide events for a week each, he finds it really hard (lots of small talk is involved) and is visibly stressed when he gets him. Has a meltdown etc. The other 50 weeks of the year he's happy as Larry. Genuinely.
He wasn't bullied at school.
He studied in a male-dominated area which really suited his strengths.
His family has a strong similar history, so everyone just deals with the "oddities" of some family members as quirks.
His DF worked in banking and had a similar life experience until banking went highly computerised around his retirement and the change was too big for him.
So suffering is not necessarily an innate part of the autism experience. At least no more than others experience. NB I'm not saying nobody with autism suffers! But the level of suffering I think may also be part of the spectrum and not a measure of the condition.
I absolutely agree there's a world of difference between someone like my DH and someone who has other aspects of the spectrum that result in them not ever being able to live independently. I find it odd that there's no way to indicate a difference without someone being offended, because it's a material reality, not a value judgement.
