Most Social Justice cultists are white dudes with some bullshit psychology defects who got sucked into the cult. That defines damn near all of the tabletop RPG death cultists and virtue-signalers, such as those who put that bullshit into D&D's 5th Edition. You'll never see this shit out of a Japanese RPG house (and they do exist) because it is so pants-on-head retarded that you have to be brainwashed or insane to think otherwise.
And that, folks, is why you see it in tabletop RPGs now: because the folks who run them are brainwashed, insane, or fucking retarded. Do yourself a favor, cut them off, and go make your own; it's not at all as hard as you think (or these people would be making the real money, in videogames).
