@apophis rephrasing my previous comments:
I have seen christians do as much magick as witches and not know that's what it was. They know so little of anything outside of normative mainstream Christianity that they can't spot sorcery or witchcraft if it isn't extremely overt and cartoonishly stereotypical. Like, where is the bubbling cauldron and pointy hat? If no talking cat or leviathan cross, is it really magick? Honestly, they probably wouldn't recognize the sigils from the keys of solomon, come to think of it. It's not that niche, but it's still not something most people know. Half the people at a renfaire probably know, but they're all edgy nerds anyways.
