Similarly, I don't understand the decisions related to the driving environment: it appears to be a personal vehicle, surely you, as the owner, can make the interior environment something that's as close to personally comfortable as possible? Maybe I'm missing the takeaway from the driving decisions.
Related, what is or isn't masking seems very confused. To begin with, it's not just code for "hiding or not hiding behaviors that appear socially irregular." But it's also not the case that deciding whether to participate in a non-working-hours event is or isn't masking in of itself.
Presenting behavior in a socialized way when necessary is a skill that's harder (as I understand it) for those on the autism spectrum, but I don't think that makes every application equivalent to masking.
There's what's that quote about good art disturbing the comfortable and comforting the disturbed.
Eating is very stressful for many autistic people because of trauma and lack of (non-enmeshing) support in childhood. They don't learn how to make a comfortable environment for themselves or that it is even possible. Every meal becomes stressful. Force feeding or depending completely on others.
Masking goes so deep, it's just not possible to easily convey with words, because after a lifetime of masking you don't even notice all the things that you do that count.
"Presenting behavior in a socialized way when necessary" has a hidden part. Presenting what behavior? To whom? Presenting autism-coded behavior around autistic people is stress-free.
If we're assuming a postmodern stance that there is no objective truth, or even a utilitarian stance that truth is a consensus, then life is reduced to some extended chemical reaction, and there is no difference between a Stalin and a Mother Theresa.
If one posits some religious definition of an objective truth, then at least there is a definition to measure against beside "Do as thou wilt".
I'm not a huge Chomsky fan anyway. Despite his appeal to truth, he tends to ring false for me.
Neither subjective or consensus accounts of truth (neither of which correspond with postmodernism or utilitarianism in the way you imply) are obviously inconsistent. Philosophers would not bother talking about them if that were the case.
Funnily enough, I can't tell which of Stalin and Mother Theresa you are worried will be confused with the other, given that many people have opposite ideas of which was moral and which was immoral.
Modern religions define objective morality, not objective truth (excluding metaphysical assertions, which are not what one usually means by truth).
