I'm completely ignorant of what D&D is and so I'll run my mouth.
You'd be surprised since Gary Gygax and Dave Arneson were both Christians. Staunchly at that. Let me show you how wrong you are with the TSR Code of Ethics circa 1984.
Point 4. All scenes of horror, excessive bloodshed, gory or gruesome scenes, depravity, lust, sadism, and masochism shall not be permitted.
Point 6. Profanity, obscenity/smut, vulgarity or words or symbols which have aquired undesirable meanings - judged by contemporary standards - are prohibited.
I draw your attention to point 10. Nudity in any form is prohibited. Suggestive and salacious scenes are unacceptable.
Point 11. Illicit sex relations are not to be portrayed or discussed and sexual abnormalities are unacceptable.
Point 12. Rape or seduction are never to be portrayed or discussed.
Notice point 13. It clearly says Sex perversion or any inference to same is strictly forbidden.
So you just lied about what is D&D. 6 of 13 points says that you're a goddamn liar.
Did you have anything intelligent to add that actually pertains to the history of the D&D game?
