FWIW, I think that is a really good way to frame it, Kent.

And Michael, I don't disagree with you. But I don't think puritanism has anything to do with it. I do think New World protestantism does. There is still 'magic in them thar hills.' I know a fair number of people, old herbalists, country people here in the Piedmont, or up in my home in West Virginia, who still work 'spells' and 'hexes.'    Still people with a reputation for having the 'sight.', etc. But, speaking in broadly general terms, there is not a strong 'fey' or as Kent puts it so well, elvish quality to those beliefs and practices. There is not a a cultural history of European paganism. We don't have daemons with the implied pagan idea of an immaterial being somewhere between human and pagan divinity. We have demons. Evil spirits, plain and simple. Little devils.    I can't think of any examples right now, but there are definitely folk songs and ballads that originated here that include talk of demons, devils, ghosts. But no daemon lovers.

According to the reference masato posted above, the same transformation has happened, to at least some degree, on the other side of the pond, also, where the ballads originated.

Magic just ain't what it used to be, I guess.
