morality is subjective and people don't have free will

[Mister Agenda]

I don't deny that there are extremists out there who may do this, though it's far from the mainstream.

Is it really that far from the mainstream in a country (USA) that's 25% Evangelical Protestants? If it was 1%, I'd tend to agree that 'far from the mainstream' is a fair description. Not that all Evangelical Protestants fit that mold, but children being born sinners is something that they teach in Good News Clubs, and there are almost 4,000 of those clubs in our schools teaching young kids that they're in danger of hellfire and the moral lesson of the God commanding the genocide of the Amelekites.

I commend you on your views of what's age appropriate, but millions of Americans believe it's a disservice to children not to instill fear of God and hell in them and the idea that hell is what they deserve as young as possible, and many of them aren't shy about taking advantage of opportunities to do that to other people's children.
