No, smart guy, you're trying to change my mind, you're doing this backwards again. You have to convince me into a conservative opinion, using facts and logic

All you have to offer, once again, is opinions.

Tell me why that practice should be outlawed.

I can feed my kid one dozen Whoppers, daily. No doctors need be involved.

Should we outlaw that?

Imagine thinking eating a hamburger is like cutting off your johnson

Uh actually you can't I'm pretty sure that would violate laws regarding neglect and welfare, but at worst they'd just get really fat. You aren't cutting off healthy bodyparts and\or rendering them sterile for life by feeding them whoppers.

Kids can't consent to taking puberty blockers and hormones because they aren't old enough to understand the long-term implications of their actions. Even if you inform them of the risks, they are in no position to understand or grasp the long-term impact it might have on their life, because their ability to consider the future hasn't even begun to develop. This is no different than the rationale for laws against pedophilia, which I'm assuming you support just like all sane people do.

We don't tell people with Schizophrenia that the voices in their head are real

Exactly, but ben shapiro made that point so therefor it doesn't count or something

I remain unconvinced, tell me why the state should intervene and prevent my family from making this choice in this completely fabricated premise

No links, no experts weighing in on the matters, just... thoughts so far. Ho hum.

"the angels told me to do it"

The same reason your family can't "make the choice" to let your kid get a tattoo. The same reason you can't hire a doctor to cut your leg off just because you "identify" as having one leg. There's this thing called medical ethics and the hippocratic oath.

Gender dysphoria is a barely understood nascent field of medicine, yet "treatments" for it are rolled out at light speed. This is like doctors who used to perform lobotomies for depression; the experts said it was a great idea at the time!

What happens if these kids decide they don't want to be 'trans' anymore?

I used to like Punk Rock when I was a kid and then I got into Metal
