I know I've said it so often that I sound like a broken record, but...
The autistic community needs to have more, and deeper, conversations about how the misogynistic, gender essentialist way autistic girls were talked about by "experts" in the 2000s and early 2010s helped pave the way for the rampant discrimination that autistic trans and gender-nonconforming people still experience.
It was very common for girls' "social skills" books and materials of that era to force performative femininity on autistic girls to "help" them fit in. (Lisa Iland's "Girl to Girl Advice" in the somehow award-winning 2006 edition of Asperger's and Girls is an egregious example of how accepted this was.)
I've said this before too, but we could fill a Neurotribes-sized book with all the ways misogyny and queerphobia have been present in "expert advice" about and for (and sometimes even by ) autistic women and girls.
