My first DM was a minister. Take from that what you will.
I gotta admit, at least where I lived, people thought D&D was for dorks and nerds. Satanic? Naw. Not cool enough for that.
funny, I've never come across anyone, christian or otherwise, who bought into this satans game business. Still, I never played in the 80s. I have had in my group a fundamentalist Christian, my wife follows the charismatic paths of Catholicism and so on. Yet they all put aside differences to pretend to be elves and kill the evil guy.
Please be careful with generalizations. I've had lots of devoutly religious people in my groups (and am one myself). If memory serves, one of the frequent contributors to Dragon in the 80s, Arthur C. Collins I believe, was a protestant minister. He did some rather neat revisions of 1e psionics.
We used to game with Satan.
Dude's a total rules-lawyer, and his PCs always have the same lame "outcast favored son" backstory.
Also, he never wanted to play the Cleric.
We ditched him.

He showed up at our game after you ditched him. He was playing an Ur-Priest when I DM'd a TPK. He didn't take it well.
He also dropped into my game too, I had to kick him out because I got sick of him insisting that I let him use Asmodeus as his PC. Freakin' munchkin.
