Couple of issues:
* if your child identifies as the opposite sex, schools and political activists will work against the parents to promote this idea, including hiding the issue from parents as long as possible
* in some states, it is ILLEGAL to get counseling other than confirming the gender dysphoria - which limits parents’ ability to fight this mental disorder
* if a girl is autistic, and essentially isn’t a girly girl, they’re several times more likely to be told they’re really a guy so let’s transition ... by counselors who think this helps the child
My comment about parenting goes back much further - to their early years, teaching them about what it is to be a REAL MAN, not going along with their girlie fantasies, which are quite common when they’re very young.
What you point out is valid, but they’re defensive measures, trying to undo the damage - if it gets to there (as in high school age), you also risking suicide if you decide to start being a real parent at that point - you have to be very careful.
