They aren't wrong per say, they're factually correct on most issues but beyond their criticism of the UCLA/Lovaas-Method model of ABA and section 14(c) (the later of which they rarely even bring up) it's all slave morality; I have projected my own transness on to them, and being medicated for it, and being with the trans community, made me realize that. Being autistic is, in most cases disabling, and as a hvn you should lucky that you aren't being treated much worse.
You will never have a real culture.
Accept your gender-affirming ABA.
