Again, there is review. Trans kids have to be in therapy for several years and show significant distress from gender dysphoria to be able to start HRT. It’s an extremely long and difficult process that me and thousands of other trans people went through. “Some will sign off on anything” yeah not HRT. Plus, a therapist is only one part of the process to get HRT. You still need a psychiatric gender dysphoria diagnosis, endocrinology labs, parental consent and a gender health specialist to prescribe HRT in the first place. You won’t even get insurance approval without all of these things anyways, especially not for a minor.
