For, what, the fifth time the sample in the study did express cross sex gender identity. They were trans kids, to use your terminology. A patient can't
desist from a cross sex gender identity if they never expressed one in the first place. Pointing out that these patients didn't seek blockers is nonsensical since blockers weren't an option at the time. The fact of the matter is that the desisters in this study:
1. Expressed a cross-sex gender identity. They were trans kids, as you choose to term it.
2. Met the assessment criteria that would be used to approve a patient for blockers.
Yes, the desisters in the study would most likely be prescribed blockers if they went to a gender clinic that prioritized affirmation.
> The difference being that teenagers who don't explicitly seek them because they don't consider themselves as trans are never considered for undergoing puberty blockers
Again, these patients did express a cross-sex gender identity, or "consider themselves as trans" to use your language. If they never did, then they can't desist from a cross sex gender identity if they never expressed one in the first place.
> No, because teenagers who don't consider themselves trans do not seek puberty blockers and are therefore never considered for them. The main distinguisher between trans and nontrans people is their self identification.
To re-use your terminology, studies found that ~80% of the children who considered themselves trans stop considering themselves trans and become comfortable and no longer experience gender dysphoria in their cis gender after natal puberty. It seems like the root of the problem is the lack of understanding that the children in the study did "consider themselves trans", as you choose to put it.
If all you're going to do is continue to erroneously claim that the patients in this study weren't expressing a cross sex gender identity ("consider themselves trans"), or baselessly claim that the desisters are actually just repressing a trans identity then there's no value in continuing this.
