I recall reading a ... pamphlet or booklet (don't remember which) that made similar claims about D&D--and IIRC cast a net wide enough to capture other TRPGs, as well. Fortunately my parents never bought into that, though they might have wished I devoted my energy to other pursuits.I think that's true, though I do recall some family friends who claimed that D&D was the first rung of the ladder leading to Tarot and eventually up (down?) to the Devil himself.
