sadly, this is not some new weird belief, but a hangover of the old medical orthodoxy.
in fact, it was the case in the '60s where if you insisted, then you were deemed insane, and since homosexuality was illegal, that made you an insane criminal, and subject to legal torture, like electroshock, aversion therapy, high testosterone dosages, brain surgery and anything else that they wanted to try.
in 1966 i had a choice: be a "man" and forget all this, or be an insane criminal .... hmmmm, difficult choice - NOT.
so thank your lucky stars it's just some ignorant doctors now, and you can actually find some that know the facts.
