Trans kids shouldn't be on puberty blockers at all. They should be given full hormone therapy at the same age their peers undergo puberty so they can have a normal development. Puberty blockers were meant to be the peace treaty. They were meant to be a compromise to hyperventilating cis people. And then they just went and demonized the compromise. I'm done.
Know a trans kid? It's your moral obligation to get them access to full hrt. Order it off the Internet and give it to them. It is your moral obligation to disobey evil and unjust laws. These laws have no more moral legitimacy than the Nazi anti-Jew laws. Anyone who respects and follows them is damned.
