It's exactly because hormones have irreversible life-altering consequences that hormone blockers are the one thing prescribed to children suffering from gender dysphoria, exactly to buy time for them to mature and be able to decide whether to go through puberty as the sex they were born at or if they want to transition.
So if you actually believe what you write, then you should be in favour of puberty blockers as an option when medically indicated.
You're damn right children can't consent to anything! That is exactly the point! Which is why the parents are the ones in charge, and why it's alarming that for irreversible sterilizing and life-altering procedures they're trying to remove the parents.
It's insane, as you very well put it. They can't get a tattoo, too permanent, but they can get their tits chopped off. Makes total sense, yeah.
And yet you're making the insane argument against the treatment (puberty blockers) that is fully reversible and reduces the need for making irreversible decisions at such a young age. And in doing so you're arguing for imposing drastic, life altering and harmful effects on those for whom their dysphoria does not resolve. It's a deeply nasty level of authoritarian overreach to be prepared to force such harm on people when we have a treatment that can mitigate it for a significant proportion of the people in question.
You keep trying to move the goalposts, because it's makes for more shock value to talk about operations. But the reality is that operations are a last resort, and one often brought forward due to immense mental harm for patients for whom blockers have not been an option. They are examples of the entirely predictable outcome of the kind of brutally inhumane policies you've been arguing for by opposing blockers.
Think banning surgeries will work? Trans people have been dying from illegal and unregulated surgeries for decades because it's for many been preferable to staying how they are.
Puberty blockers are risky and can have non-reversible consequences. Your wishing them not to doesn't change that fact.
Plus, on top of the medical risks, starting on puberty blockers will make confused kids who didn't need them more likely to get surgeries later. That's bad, and yes, it's a trade off between not unnecessarily medicalizing confused kids and "helping" "real dysphoria" cases earlier. And I'm telling you very clearly that the answer depends on how many there are of those, but you don't want to engage with the question. Because there just aren't that many "real dysphoria" cases.
And let me preempt your next bad argument: No, a doctor can't tell them apart. That's where we are now, and they get a "dysphoria stamp" after a visit. The incentives are not aligned, they just want the money.
The goal posts have always been firmly on "Don't mess with children". I've told you many times, nobody cares what adults do, sex change surgeries have been around for a long time and nobody cares. Nobody wants to ban them on adults.
Puberty blockers are not fully reversible. It isn't like someone hits a pause button on puberty, as much as people like to portray it that way. I Am Jazz even displayed one of the consequences -- Jazz had inadequate penile growth, and thus wasn't really eligible for the more common and preferred vaginoplasty. And you're definitely messing with height, as any surge in estrogen can cause the growth plates to fuse -- completely non-reversible, to the dismay of all kinds of people.
Time marches on in the human body, whether we like it or not. Now, show me a "perma-kitten," a cat developmentally frozen in full kittenhood, behaviorally and all (something I think would be immensely popular with some crowds) and then undo it, only then will you be close to this pause button which puberty blockers cannot well emulate.
