It's like Sir Humphrey explaining to Jim Hacker how to rig a questionnaire. "Do you want to instill a bit of military discipline into the lazy, feckless workshy youth of today?" versus "do you want gangs of disaffected youth with military training roaming the streets?"
Similar thing going on here I think. I suspect "do you want to put confused teenagers, many of whom may be confused about their gender identity due to autism or past sexual abuse, on a one way path to irreversible surgery, sterility and a lifetime's dependence on drugs?" You might get a somewhat different answer.
