Sorry for putting Gideon's words inside your quote box here
@angrysoba; I just wanted to reply to this bit.
I don't buy the idea that the original approach was to "manipulate and emotionally/physically abuse the kids until they stop saying things about their gender" because kids did not yet have the words and concepts to talk about their "gender identity," and they definitely didn't have anyone giving them hope that they could physically transition from living as one sex to another. The fact that almost everyone accepted their birth sex was largely the result of them understanding that there wasn't really any viable alternative. This approach cannot be resuscitated without heavy-handed political intervention, and even then it might just be adding an onerous commute in order to obtain treatments in a nearby jurisdiction.
As to the competing medical models (therapy first with medical pathways heavily gatekept vs. patient-led gender affirmation) I'd say Gideon is substantially correct about those two competing models.
Advocates of each have been saying that they have good evidence for their preferred approach, but probably Guyatt is correct that they are both incorrect about this. So far as I've seen, we've yet to witness a substantially-sized well-designed study which directly pits the older approach against the newer one, randomly assigning patients to each treatment group.
