> undergo their AGAB puberty against their will
It's also weird mental gymnastics like this that people are pushing against. For anyone who is not familiar with the acronym, AGAB means "Assigned Gender At Birth", and is push back against the fact that we broadly lump all people into either the male / female camp when they are born. It can be useful when talking about gender norms, etc – which are discussions worth having. But when you start to move into the region of "biological sex is unimportant" it takes on an entirely different slant.
"AGAB puberty" is an oxymoronic statement. If the gender was merely "assigned" to them, then why is their body naturally going through puberty in a certain direction. It's not their AGAB, it's their biological sex. We are not saying "this is a boy" and then giving them testosterone when they hit 12 so that they match their "assigned" gender. Their body is the body of a boy which naturally produces (much) more testosterone (and other obvious hormonal and physical differences) than that of what we broadly call a girl.
Nobody is FORCING anything – that is just something our bodies do naturally because we are a sexually reproducing species of mammal so our DNA causes us to split broadly into male and female.
