Where are you getting these details about Jazz's surgeries?

From Jazz's literal mouth because he and his whole family participate in a reality show about his pain ever since they had that one viral youtube video where he's 3 years old and wearing a girls' swimsuit and talking about how he's so happy he's a girl now. His family wouldn't just let him wear a fucking rainbow swimsuit without forcing him to try and become a straight girl.

His father admits that he would regularly scream and lose his shit at 3-year-old Jazz for playing dress-up and being too feminine in general, especially when he wanted to wear dresses outside the house. His parents almost divorced because of what a raging piece of shit he was, but his mom still clearly agreed on some level because she believed that femininity in her male child was a sign of some deep psychological disturbance and she found an easy solution on an internet forum.

There is a picture online of Jazz's father holding him at school when he's wearing a princess dress (some father's day event) barely able to contain the deep level of disgust he has for his own child which turns his attempt at a smile into a sneer. He admitted that the morning the photo was taken, he had another screaming meltdown over the fact that his son wanted to wear a dress to school, but this time Jazz's mom convinced him to let him because an internet forum told her he was a little girl trapped in a boy's body, not an irredeemably worthless feminine male.

So yeah, then they made their viral video about how 3-year-old Jazz is truly a girl inside and that's the only reason they let him dress and act a certain way. It blew up and they got so famous they got a reality show out of it.

Now they like to sit around in their little mansion that they bought with the money they got from broadcasting their son's living nightmare and talk about how Jazz's mental and physical health is so fucked up because he doesn't try hard enough and he's mean and he's ungrateful and hey, let's take him roller skating and ziplining even though he's morbidly obese (also isn't it hilarious and disgusting how fat Jazz is? let's ignore the estrogen we put him on) and on his 4th revision surgery because his genitals keep splitting at the seams. Oopsies teehee does he need another revision? Phew because if he left for college and stopped doing the show, mom and dad would have to sell the mansion and move to a condo and her brothers would have to get jobs.

In a shocking moment of self-awareness, Jazz went to a "hypnotherapist" and experienced "past-life regression", where in a "past life" he was a gay boy who was rejected by his family and homeless on the streets.

Jazz's family threw a party to celebrate cutting off his penis when he was 17 years old. Jazz's family tracks his every move (he is 22) and he needs explicit permission to go anywhere. If his phone tracker shows that he is somewhere different, his family shows up to where he is to harass him about "lying".

Jazz's family wants him to stay home and not go to college because he's "not ready" (their wallets aren't ready). Then when Jazz breaks and says he doesn't know if he wants to keep going to college, his family still degrades him for "giving up".

I imagine that the money from the show is legally Jazz's parents' and not his, increasing his dependence on them.

The show mainly features his severe physical and mental health problems.

All of this is public. Most of the show can be found for free on the internet. The show is called "I am Jazz".

They're pretty good at picking it. Transition regret is of the order of 1%.

We already talked about the way those studies don't include people who commit suicide and only include respondents in their data (those who respond are more likely to not have regret). They also discount your data if you no longer identify as transgender. Have you not looked at a detransition study since 2016? Newer surveys show closer to 13%. And in the largest study on detranstioners to date, only 24% of them reported to their clinic that they were detransitioning. And we can reasonably assume that the patients who agreed to participate in this study were far more likely to report their detransition to their clinic instead of continuing to keep their regrets to themselves.

You can generally tell by puberty age if the dysphoria is worsening or will resolve.

Actually kids who get gender dysphoria at the onset of puberty (ROGD) are much more likely to regret it and detransition.
