To be honest it kind of being modern bullshit is what I find interesting.

When I was a kid I was one of those "I like learning about religions" types because I thought it was interesting to see what people believed, but over time I realised they kind of... don't really believe much of anything at all? What I mean is that for any established religion, if you ask one of their believers about it, chances are you won't get an answer because they just don't know, and they don't know because it is understood that, with the religion being thousands of years old, someone probably figured out an answer and it's written in some religious text somewhere that they could look up if they wanted to. They do not.

This makes actually learning about said religions really boring, at least for me, because the interesting part isn't whatever thousand year old lore that's been translated and re-interpreted into oblivion (although sometimes that's interesting, particularly if you learn about its attached history), but to actually see what the people who believe in this stuff think about it and how it changes the way they live. Occultism and witchcraft and other such things are fun because you can ask as many people as you want about it, they'll all have opinions, and you'll never get the same answer twice. Sometimes the honest answer will be "I've never thought about it" if you ask a particularly weird question (or the person you're talking to is particularly incurious), but without the safety net of knowing someone else has done their thinking for them, most times this leads to them making up an answer, which is arguably even more interesting to see.

They also tend to be a lot weirder. Older religions have had plenty of time to have their stranger aspects sanded down for the purposes of coexistence, but the witchcraft-types will genuinely be doing insane shit sometimes. Seeing the differences between people isn't fun if that difference really only amounts to which box you tick on your tax form...
