They definitely are doing it responsibly; I just don’t agree with it. I’m generally against any form of plastic surgery or body modification. Teenagers can also be hormonal, stupid, heavily influenced by others, and rebellious. With current cultural norms, at least in the US, I wouldn’t trust any child to make an adequately informed decision, especially without heavy influence from politically active parents. I work with children, and know multiple prepubescent boys and girls who talk about being the opposite sex or about being some other form of LGBTQIA+ when they haven’t even developed sexual attraction yet. That’s another conversation though, lol.

They are just one hospital, and they still do chest surgeries on children 15 years or older.

If a child is under any psychological distress, permanent physical modifications shouldn’t be an option: the distress is psychological, not physical. Psychological distress should be addressed by a psychologist, maybe a psychiatrist, not a surgeon. Personally, I believe that care should include helping the child to be comfortable with themselves in their own body, as that will help not only in the case of the child’s current gender dysphoria, but also later on in adult life when reality really hits you.
