I've taken a few courses in uni any classical history and anthropology. Including one that was on a random topic that was TBD when I signed up. It turned out when I showed up day one to be about magic in classical antiquity. It was a good course, but the proof decided to do the last lecture or two on, more or less, tying things loosely between back then and today.
That's when half the class decided to raise their hand to say that they were wiccan or some other similar flavour of spirituality. I kinda felt bad for the guy, that day, he wrote a book on alcohol in antiquity, it was a fascinating read, I bought it without having to buy it for a course. But that day, there he was, dealing with a bunch of students insisting on arguing minutia.
