You mean gender dysphoria. Body dysmorphia is also something trans people experience. You’re basically making the “they’re killing the twinks!” argument with absolutely no evidence for diagnosticians leading patients towards transition. My experience as a trans woman is that I had to fight my doctors to believe me, and this is a common experience in my circles. I know dozens of trans people, and not a single one was told by a doctor that they were trans. We call it the prime directive, and we even apply it between friends.
