If we lived in a world where being trans was something people understood, someone could have looked at me at 12 and said “hey that sounds like trans stuff, let me ask you some questions about gender”.

This this this!

I knew since I was in elementary school it wasn't socially acceptable for me to wear a dress because I saw no other boys wearing one. So I crafted elaborate fantasies where I was "forced" to wear girls clothes because I couldn't bear the idea of being responsible for wanting to be feminine.

I'm well into my adult life now and finally accepted myself, and a really backhanded compliment I got was "at least now that you're older you know what you want". Thankfully I was very willing to point out to them: what if I had seen so many other boys my age wearing dresses? What if being trans was normalized then? I guarantee I would've started presenting as a girl as a early as elementary school if I didn't feel like I would've been judged or punished for it. Then I would've had years before puberty to discern whether this was something I wanted to commit to.

So yeah, the idea that kids can't make those decisions is completely transphobic. No one should have a problem with stalling puberty; if they're too young to decide, then their body shouldn't make that decision for them. It's literally a question of bodily autonomy that no one else should have the right to decide.
