@hubrys As I've explained elsewhere, Trans so-called "science" is famously, FAMOUSLY, politicized, biased, whitewashed.
We learned from covid that even JAMA does bad "science" & deserves doubt.
So please take your fake Lysenko-ist study & cram it.
FTM Matt Rey: "I have experienced side effects...that I would not wish on my worst enemy...that even doctors were not knowledgeable enough to tell me about."

"Trying to be happy whilst living with this regret is a constant struggle. My body spasms have become more frequent. I wish I never fell for the lies of 'gender affirming care' I wish all of this pain would stop.
These monsters medicalizing kids deserve to rot behind bars."

That regret does not sound "scant" to me.
Or what about Kayleigh Scott?

Sounds like suicidal ideation.
Kayleigh Scott - Say her name, @hubrys !
Say her name!
While you're at it, tell me - is the following a Genuine Man(tm)?
Or example of extreme self-harm?
(Note: Picture was taken in public and, under rules for shirtless MEN in public, is acceptable worldwide. Twitter allowed it - and, I believe, did not even 'warn' it.)

With exceptions - Exceptions for genuine intersex, XXY, hermaphrodite etc. -
Those proper exceptions aside, the majority of Trans surgeries today are examples in and of themselves of self-hate and, you could say, self-murder.
OF COURSE the person is going to regret them - Later on, to the extent their mental health improves. And to the extent that someone asks them honestly.
Mental health issues - like Gender Dysphoria, Body Dysmorphia, anorexia, self-cutting, etc. - are not cured by surgery.
Western society, with Trans surgeries booming, is about to learn all this in hard way.
