What’s the benefit of this? I don’t understand how that benefits parents or children. Who cares if the kid is a boy or a girl? What if their parents are abusive? School is part of where identity develops, to rob kids of that seems messed up
It's not about the parents or the children. There is a right wing media apparatus doing it's best to rile it's viewers up over trans issues. Right wing parties can benefit from a lot of media reinforcement by making gestures towards those issues which those viewers, which happen to overlap with their base basically 100%, are being riled up about.
There is no benefit from this, other than buying votes from right-wing loonies.
Realistically, this is going to kill a lot of queer kids. There will be an age gap between the trans youth over 16 today, and the ones that come up after this is repealed -- Not because they were somehow "converted" but simply because a lot of them won't live to adulthood because the prospect of living through their teens in the wrong skin, with the wrong name, and wearing the wrong clothes is that torturous. This will kill kids.
It is a program of genocide. Not necessarily specifically coordinated in this case, but mostly Christian nationalist groups, mostly based in the USA, have been deliberately spreading it for years.
