I wouldn't rule out that that "old religious wackos" may be more descriptive than "elite country club snobs" in this case.
This seems closer to the "Dungeons & Dragons is SATANISM!!!!! OMG!" stuff from the 1980s.
I kinda feel like it’s old GOPers trying to grab at any straw they can to get a leg up on the opposition, and being too out-of-touch with younger people to realize how many they might turn off by bashing the game. I doubt they know much if anything about the game, they just figured they could make it sound “weird and scary” in ads to use as a wedge.
