Why do you consider medical transition as harmful anyway? Most of the operations have no significant risks and you get well informed before even getting the chance of having them performed and they usually have a much higher satisfaction rate than other medicinically necessary surgeries like knee replacements etc. And if you want to use some "but think of the children" bullshit, assuming you live in either the USA or the EU, they get puberty blockers at most, which are also in use for several other things and proven to be rather safe, and then when they get older they finally get access to real HRT which also doesnt pose much risk to their health since several years as long as they take the right supplements alongside it as with a lot of medicinic therapies.

And suicide is actually legal in a lot of countries fyi
