Why so much witchcraft?

I don’t have issues with what anyone paints. But just wondered why all the diamond art sites seem to have tons of witchcraft/ spirit type stuff. Honestly don’t care but it’s just not something I’m into. I don’t like tarot cards, witches etc. I had a lot of nightmares as a kid and also it’s just not a theme I go for. I am sure someone is going to be offended but just curious if anyone else noticed or had suggestions for sites with less of that.
