Actually “leftist nihilism” is a better term
How so?
Nihilists wouldn't care about what anybody else thinks. Or if they do care, it's not that big a thing with them.
Cue John Goodman: "Nihilists! **** me. I mean, say what you want about the tenets of National Socialism, Dude, at least it's an ethos."
People don’t understand “nihilism”.
