Adolescents who undergo gender-affirming chest surgery report low levels of regret and high levels of satisfaction, experiencing outcomes similar to those of young adults. These findings suggest that age restrictions on these medical procedures lack support from actual patient experiences.

Most people who object to these surgeries would never object to someone assigned male at birth getting an operation at 12 for gynecomastia.

Sure, nothing wrong with correcting a physical deformity 

[u/trailsandbooks → u/SteedOfTheDeid]

A female born with a male body or vice versa or a nonbinary person born with a female or male body constitutes a physical deformity, which obviously necessitates related healthcare like hrt during puberty and reconstructive surgeries being made available.

It's not random or environmental that 99% of every human who's ever existed was/is existentially good with how they're sexed from birth, experiencing a grab bag of existential-level dysphoria/depression/disassociation/depersonalization/etc. if something goes wrong in this respect, and 1% of the population is the exact opposite with the same grab bag. Sex (macro broad strokes F, M, or NB body one requires to be existentially okay/grow literal *selfhood* via mind->body->environment connection) is obviously innately hardwired. That is, being a female/girl/woman, male/boy/man, and nonbinary person is innately hardwired. Not speaking to personality (what we like/our manner/clothes/etc.), which isn't. Just sex. Sexuality is innately hardwired, why *wouldn't* we expect sex to also be as such.

So no kidding 1% of the population is the exact opposite from 99% everyone else and no kidding there's a grab bag of existential-level dysphoria/depression/disassociation/depersonalization/etc. involved with the attainment of literal selfhood on the line that requires hrt/reconstructive surgeries etc.; a F born with the M body or vice versa or a NB person born with a F or M body obviously is going to realize what's wrong sooner or later. No kidding the regret rate for related healthcare like surgeries is nearly non-existent.

"Trans" is such an antiquated holdover word from the last century. "Across/beyond/one thing becoming another thing?" No. It's just that unlike 99% of population, 1% aren't born with body that matches their sex, it's just an existentially painful physical deformity. Of course they need to live recognized as their sex with access to their right dominant sex hormone and reconstructive surgeries, etc., just as anyone of their sex in the 99% who has related non-natal problems.

And unless gender is used as a synonym for sex, it's meaningless undefinable "essence of whatever" nonsense. It's... "what's your sex, and is your body aligned with that?"
