You know what was pretty eye-opening?

Early cinema. The earliest films from most countries, especially European countries like Italy and France, have a pretty firm occult standing.

I do wonder if some of the giant "fires" that they had to wipe out a large portions of those films was literally to get rid of evidence.

Anyhow, these people have been occultists for generations...so common knowledge for them isn't necessarily the same as for an ordinary person. But the stupidity and hubris definitely seems to have been ratcheted up a bit.
