Christians teach children that if they don't get bathed in the blood of 2000 year old dead Jewish man, they will burn forever in eternal conscious torment.
I think people can certainly ethically cross boundaries in raising their kids, though perhaps no law is broken and the implementation of law might lead to authoritarian overreach and violation of human civil rights.
There is plenty so far that we tolerate with conduct of parents who are Conservative Christians for example, even though much of it is incredibly harmful to their children. So I find it ironic that this is a big issue for the Right.
I think there is much about some of the LGBTQ culture which is in its infancy and there are certainly some expressions that for me cross the boundaries. More properly parents shouldn't be seeking to impose an identity or mode expression, but seeking rather to encourage and guide your child on their unique journey of self discovery in the world. Should this episode require this much attention when we have so many giant issues in front of us, such as climate change, healthcare, infrastructure, wealth inequality.
That's really what all these "social issues" are, red herrings from the truly major issues which impact all our lives and which the GOP and Right Wing have no solutions for. Nope, the Red Pill it turns out is really just a nihilistic acceptance to do nothing to try to change the world from collective action, but to just accept the world as it is, no matter how ****ty it may become. No thanks!
