I'll quote this from your link again. Take a breath and stop being so emotional.
“It’s really, really distressing to read sometimes, where you have people who have very strong gender dysphoria and want to transition, and their therapist says, ‘Well, we need to first cure your autism before we transition,’ which is wrong on all levels,” Warrier says. “We want this study to really demonstrate that both of these things can co-occur, and just because these things co-occur does not mean that one should be denied.”
Directly s on your implication that an autistic person shouldn't be allowed to make the same decisions a non-autistic person is allowed to make., doesn't it?
