but prebubescent children get NOTHING in terms of medication, hormones, surgery, etc.
Pubescent children can get put on blockers in order to delay the onset of puberty. These have no known serious side effects for children and just put the brakes on natal puberty. Natal puberty produces some changes to ones body that can exacerbate gender dysphoria for Transgender people and be costly to address via surgery and other procedures. It is undeniably ideal for Transgender children to not have to go through their natal puberty. Cross-sex hormones, which DO cause changes in the body are not typically introduced until age 16 or so recommended by their doctors and nobody is getting surgery until adulthood. There will always be some people for whom transition may have been the wrong choice and desire to detransition. They should be supported and affirmed in that choice. However, what I am most concerned about is people freaking out about a handful of detransitioners or people regretting their choice and imposing new and unreasonably stricter rules on others whom literally are going to die if their dysphoria is not addressed. Bigotry against Transgender people, especially in the UK, is a serious problem and people like JKR are promoting ideas and theories and information that is harmful to the cause of Transgender equality and access to transition-related care.

So, if I seemed a little concerned about that in this thread, this is why. Thank you for being supportive and trying to understand.
