It doesn’t matter. As I’ve said I’m speaking about people expressing trans identities in adolescence, regardless of onset.

But of course it matters! Not all "gender dysphoria" is of the same nature, nor does it have the same cause. GD of childhood onset is very different to GD of adolescent and adult onset. Both within each sex, and between the two sexes.

A same sex-attracted male of 16 who developed childhood GD because the adults in his life shamed and punished him for liking "the wrong toys" and for being what they considered "girly" or not sufficiently manly is entirely different to an opposite sex-attracted male of the same age who developed GD because when he was 11-12 he started borrowing the undies or intimate items belonging to his mum, sister or gran to masturbate in/with, and after finding he really got off on it developed AGP. And GD in each of them in turn is different to the GD of an awkward autistic boy of the same age who hasn't figured out his sexuality yet but in the past year has been groomed into wanting to be/thinking he's a girl by adult predators who search the internet looking for "eggs."

Saying "it doesn't matter" that what's going on with these different groups of young people is not at all the same and treating them as one undifferentiated mass is doing them great harm.

Moreover, GD in females is entirely different to GD in males. A 15 year-old female who developed adolsecent-onset GD because of sexism and internalized misogyny will have little to nothing in common with a male of the exact same age, class, locale, etc who developed adolescent-onset GD because he has an adolescent male libido and has been steeped in sissy porn.

As for people "expressing trans identities in adolescence" - that's a far, far bigger group than kids with childhood-onset and adolescent-onset combined.

Please explain how the medical interventions and cruel lies that gender ideology advocates insist minors be subjected to in pursuit of "early gender transition" doesn't amount to child abuse.
