No one has ever made the argument that this is new. The statement is that it's more visible, blatant, and overt. Death of a euphemism kind of thing. It doesnt matter if you heard this rhetoric 40 years ago, because it WAS around then. Its just louder and more blatant now, and being furthered by people getting into power who believe it, but are less educated than the people who dreamt it up. The Boeberts and MTG's of the World, ineffective politicians whose sole job is to obstruct, do damage, and stir the base with inflammatory rhetoric. No one is making the contention that any of this just popped up recently, or began with Trump, or even will end with Trump. Bannon kind of let that cat out of the bag when he yelled at some podcasters that Trump is just a figurehead and that the endgame has nothing to do with him
