Earlier quoted context omitted.
Funny thing is, I see certain political beliefs -- like contempt for religious freedom (and other freedoms centered around belief and conscience) -- as existential threats to a free and open society. I think I have a good case that they're a far more direct threat as well, as well. I could even make the case that it's a fundamental contradiction, maybe even a lie, to pursue a "free" society by suppressing freedom. :P
I don't disagree that contempt for freedom of thought--which includes the freedom to think thoughts and believe things that are false--is a serious threat to a free and open society. But I would also point out that, taken to its logical conclusion, this is an argument against public education in general. Any system of public education will end up teaching children things that their parents disagree with on freedom of…
But they're not an unmitigated blessing whose opinions should supplant those of parents in all cases either. So I think that it's really good that people have the option to send their children somewhere that isn't a public school system (including a private school or homeschool, possibly even with vouchers). That's a simple, useful check on its power -- and explicitly seeking to remove that check with the goal of changing the way children think is Kinda Creepy or worse. We don't need no thought control...
