As an Autistic trans man of his own genders, I was also taught that shit from family, a teacher assistant (whom I could care less if she ended up dead because she was mostly an ableist piece of shit), even from an older sibling I no longer speak to due to him being transphobic towards me. It was also reinforced by the people I've interacted with online so what you've said about Autistic folks who presented as Autistic girls and women hit very hard, especially with the bluntness of our honesty (I had bad reactions towards my own blunt honesty, leading me to sugarcoat shit and leading me to second-guess my own honesty and doubt it).
Thanks for writing this, Shamiha.
