I’m sorry, but this is an awful set of premises and conclusions.
First off, yes, kids _do_ get a range of psychological tests when working with gender dysphoria issues, INCLUDING autism spectrum disorder.
You can still say Aspergers if you like, but it’s referred to as “autism spectrum disorder” for a good reason.
“It’s not PC to…”
“People are scared to..”
That’s utter nonsense.
Professionals work with these children for the best possible diagnosis for their issues so they get the best possible treatment. Teachers, psychologists, psychiatrists.
It’s not easy to get proper diagnosis either. The medical profession, schools as a whole tend towards conservatism, working with whatever worked 5-10-20 years ago. Trendiness is rare in institutions despite hysteria from clickbait articles and preacher pulpits and Twitter/Youtube political commentators.
