If you block trans teens from receiving gender affirming care, some of them will commit suicide.
“They will kill themselves if you dont do x” isn’t an argument. If anything it’s a problem statement.
If you let them destroy their young, still forming bodies many of them will regret it and commit suicide later when they realize they have irrecoverably destroyed their natural sexual function. They are children with a limited capacity to understand the totality of how this will impact the rest of their life. If doctors and schools communicate openly and honestly with parents (which they don’t) the situation can be handled in ways befitting a minor.
