After reading your first paragraph, I was already drafting a slightly standoffish response in my head, to the effect that the children who grew up on our sanitised fairy tales seem to be blowing each other's heads off on the battlefields of 2026 with undiminished enthusiasm and sadism, and the only difference is that now more of them need a Xanax prescription afterwards. I appreciate that you actually addressed this view with less snark than I was able to.

There are cultural differences here though. Brüder Grimm aren’t quite as toned down in Germany as we see in US stories being Disney-fied.

The U.S. was born out of Puritanism. That prudishness and absolutism continues to echo through into its modern culture. Most people don’t even realize it does.

    Forasmuch as the Feasts of the Nativity of Christ, Easter and Whitsuntide, and other
    Festivals commonly called Holy-Dayes, have been heretofore superstitiously used and
    observed Be it Ordained, by the Lords and Commons in Parliament assembled, That the
    said Feast of the Nativity of Christ, Easter and Whitsuntide, and all other Festival
    dayes, commonly called Holy-dayes, be no longer observed as Festivals or Holy-dayes
    within this Kingdome of England and Dominion of Wales, any Law, Statute, Custome,
    Constitution, or Cannon to the contrary in any wise notwithstanding

It's funny, because I think that to certain other cultures, for example the Japanese, Christianity (and other Abrahamic religions) are Lovecraftian horror. Shinto isn't really a religion in the sense you or I know it, it's more of an animistic set of practices related to daily life. The kami are very much real to the Shintoist mind; the big ones, like Amaterasu, don't have much of a direct interest in your life, and the little ones are more like neighbors. You have to pay them their due respect, and they could grant you boons if you made them the right offerings. OK, now tell this person that there is only one all-powerful god who lives in the sky, that he is keeping meticulous track of everything you do, and that he will doom you to eternal torment if you do not meet his threshold for good behavior, or even fail to properly believe in him. (Japanese have a concept of hell, borrowed from Buddhism, but it's much more a place of repaying karmic debt than of eternal suffering. Japanese hell is time-boxed.)

To me there is a reason why when Japanese media invokes Judeo-Christian themes, it's with a sense of grandiosity and terror. Think all of Evangelion. Or how in a JRPG, any time there's a "pope" character, he's the bad guy (or at least the penultimate boss just before God himself).
