Beyond even that, assuming it would have no healthcare long term effects, it would still have massive effects on a person. If a boy feels alienated from their birth sex, watching them all develop body-hair, and become more masculine surely won't make them feel less alienated.
Absolutely. Any kid on puberty blockers will certainly not have a regular childhood, not when all their friends go through puberty with all the physical and mental changes that comes with. They will be left behind, unable to connect with their peers, and forced to have a pseudo-puberty later in life. And then you have an 18+ year old going through the phases of mental and physical maturation they should have gone through half a decade earlier. They still won't be able to connect with people their own age, who have stabilized and moved on to continue maturing regularly.
Who can they connect with at this point but other similarly immature transgenders? Is it any surprise that many transgenders seem a bit immature, focused on toys, yet overly sexual all the time? They're in permanent puberty, aren't they?
Puberty blockers might be reversible in the sense that a patient can have a natural or artifical puberty later in life, but it won't be the same. The patient will not be able to have a regular childhood nor even a normal young adult life, and I wouldn't bet that they can ever really fully catch up with the rest.
The full effects of puberty blockers are not reversible, and anyone advocating that this stuff should be easily accessible wants to actively harm children, even if they think it's in the best interest of those children.
At least that MacLeod dude wants to level the playing field and get
everyone on puberty blockers, so they're all gonna be fucked up in the same way. Normalize the induced developmental disorder. Surely, nothing can go wrong with every 18 year old young adult of a generation about to go to university or work going through a delayed puberty.
