I don't know, I personally have trouble communicating with some fellow autistics sometimes. Autism is a spectrum after all, and I think individual autistic communication is also informed by cultural expectations (ethnicity, race, class, etc) albeit in a different way from how NT communication is shaped. Given that my cultural background is quite different from a typical person, I often run into problems when communicating with other autistics as well.
That would need a whole article if I were to explain my background, but to put it succintly, I'm a third culture kid who lived in the US and went back to Indonesia.
