I am fascinated with with the Satanic Panic of the early 80s. Partially because I lived through it but also as someone who isn't religious I found the whole "panic" to be very confusing.
Here is an article that covers part of it. D&D makes brief cameo.
A Brief History Of "Satanic Panic" In The 1980s
To get an idea of how serious people took this stuff here are a few other posts I made with links to articles and videos.

Here is a direct link to the D&D video (starting around 3:30)
And a few other videos I have watched, but not otherwise shared.
I LOVE that he used my Mystery Science Theater 3000 version of the cover of Dark Dungeons track. It is too bad that no more of this series was produced. I also got a kick out some of the picture of old D&D stuff. He had another series on his older account. https://www.youtube.com/user/Godlesspanther/videos
The first one is here: https://www.youtube.com/watch?v=jPMtVjg636E (the production values are a bit low).
There is a playlist by another user of all these videos, warning there is a lot of crazy here.
I have to admit my own (at the time) anti-theism influenced my early D&D games. So lots of undead, demons and (you guessed it) witches. An immature reaction? Yeah. of course! But I was a teen at the time; by definition, immature.
It has though been fruitful in one respect, I have a ton of material that I wrote back then that I'd love to pull out sometime.
