I think we all know we did a lot of dumb shit when we were younger. We embraced fads that we didn't really like, we tried to hang out with "cool kids" whom we didn't really like, we pretended to like the things our friends liked and pretended to dislike the things they disliked, etc. A huge part of childhood and adolescence is basically "trying on" different experiences to see what you like. And I'm sure now with the growing acceptance of trans people that some kids are "trying on" being trans (and other non-heteronormative experiences) for a little while but aren't really gender dysphoric.
It's certainly fine and right for a parent to worry that their kid is going to make a life-altering decision that they'll later regret and can't take back. But the proper way to address those concerns is with appropriate parental, medical, and therapeutic input to ensure that people who do medically transition really want to do so. Not fake science justifying state bans on a treatment that has a tiny regret rate and that when refused leads to countless mental health problems for actually trans kids and teens, many of whom are driven to suicide. And while I certainly empathize with the parents who seriously grapple with these issues, I have zero empathy for those who treat their own children like property and think its their right to force their child to be whoever and whatever they want them to be. If those parents would be less selfish and take their own parental responsibilities more seriously, this wouldn't be a political issue at all.
