I'm from the South and there's a lot of ambient religiosity there, for cultural reasons, and it sometimes gets mistaken for piety or real reverence.
I think this is generally the case, in any region; that there are ethnic artifacts, or habits, that have sort of been integrated into the local religious practice. But my impression is that Protestants often can't tell that they've done that because it's all sort of "social/philosophical", rather than "traditional" (like with Catholics, where you can point to painting styles or relics and processions, and whatnot). Like, claiming it's unchristian to drink alcohol, or claiming that everyone can speak in tongues or handle snakes or whatnot. It _sounds_ like theology, but it's just whatever they're into around there.
And I tend to lump the Young Earth stuff into the same category. There was a surge of scientism, in the American past, and that is a locally-derived reaction to it, that doesn't translate well to someone sitting in Siberia, Buenos Aires, or Paris, because we are raised on people demanding we take a stance on that. We are very focused on the New Testament and the Traditions.
