Generally speaking, I think the conversation about gender affirming care for youth should focus on allowing parents to make the final decision, and on pushing back against bad journalism that leads parents in the wrong direction on the science.
Politically, the GOP has made a big bet on parents rights. So it makes it easier to argue against state bans to use that pre-existing propensity to support parents' deciding for their kids.
But that's not ultimately why I think it's the right approach.
