But lots of authors in the straight, white, cis male category have had disabilities and still got published and became part of Great Literature. I think some were likely aneurotypical, too. It's just that the privileges associated with being white, cis, male (het not always necessary) overcame those negatives. Even if they could and did write diverse and inclusive books, society intentionally excluded similarly-situated individuals (that is, with similar disabilities or health problems or whatever) because they were not white cis, (presumed) het males.
