As the shaky evidence base for youth gender medicine has become better known, activists have retreated to an argument from authority. Never mind the Cass Report, whose findings resulted in the closure of Britain's leading youth gender clinic. Never mind the study by a leading American practitioner showing that the treatments she championed did not improve minors' mental health. Never mind reports that some adolescents were being put on a medical pathway after only a single clinic visit. For advocates, the important thing to remember was that "gender-affirming care" for minors-puberty blockers and hormones, plus surgery in rare cases-was endorsed by all of the major American medical associations.
