Neurotypical people have (with few exceptions) a similarly poor theory of mind of what goes on inside autistic/Asperger people. But because the latter are a minority, it is those who get stigmatized.
But it seams like you are missing a part of what poor theory of mind means here. It means that you don’t understand yourself and your own minds tendencies just as much as you don’t understand other peoples perspectives.
The pondering is not intended as a truth about the authors mental state, it is simply my intuition of an idea that a mind that would write such a statement might be blind to.
But who knows... here I am on the internet trying out my ideas.
It makes sense that someone would come to that conclusion given certain beliefs about the world.
I call it ridiculous cause I think it is narrow minded and not optimal to think of things like that.
