That's true up until the point they actually infect the game books themselves. The Satanic panic managed this feat to a staggering degree in the '80s -- if you remember 2nd Edition D&D, they excised all references to demons, devils, demigods, gods, and patently evil things like the assassin class. The difference is that while I never believed that TSR did that for any reason other than at-best a desire not to rock the boat and keep their audience as wide as possible or at-worst total corporate cowardice, nowadays it's just as likely that SJWs are running the frigging game company and writing the supplements. White Wolf in the '90s was just a harbinger.
I can't speak authoritatively on this because I haven't bought a RPG book in years and haven't purchased them regularly since 3rd edition folded, but the things I see online don't really make me eager to try.
