Just in case you or someone else is genuinely not aware: Transgender care for anyone before puberty is entirely social - let them wear their preferred clothing and use their preferred name and pronouns. This is not permanent. Transgender care for those who have reached puberty but are still minors involves the same social things, plus puberty blockers - puberty blockers delay puberty while you take them. If someone took them for 6 months, then stopped, their puberty would start back up as normal. This gives kids more time to grow up without having permanent changes that they would have to work hard to reverse, like a trans man having to deal with getting rid of breasts later in life. This is exactly the opposite of letting minors make permanent changes to their biochemistry. Given the suicide rates, this is also the opposite of “hurting themselves”. The treatments you seem worried about are not available to minors. The medical standards of care for those age ranges straight-up do not include them, and it would be really weird (and likely considered unethical) if a doctor ignored the standards of care and did them anyways. The care standards give younger people time to see what it feels like to live as another gender, while leaving every option open for them later as they grow up.
Actual transgender care for youths also reduces suicide risks substantially, which is a lot more permanent than temporarily delaying puberty for a while and wearing a dress. Though, given how extremely low detransitioning rates are, it is likely to end up being permanent, the options available to young people aren’t difficult to reverse.
All this is why you got the downvotes - you are arguing against something that does not happen, using dramatic language, in favor of something that leads to a lot of self-harm in children (literally over 90% of trans youths have attempted self-harm at least once, per a 2017 University of Cambridge study).
