There are some autistics who would have difficulties in nearly any society but one could argue that it’s mostly due to comorbidities.
That's such a good point! One could argue that an autistic person has trouble socializing not directly because of their autistic traits, but because allistic society has bullied them enough to develop social anxiety. In this case, the actual "disorder" that is preventing socialization is social anxiety, but the root cause was allistic bullying. Should allistic culture change to accept and embrace autistic traits, then there would be no problem, and the autistic person wouldn't be considered disordered. Is that in line with your argument?
