But it is Nationalism though, is it not? They are trying to protect America as they see it (which in their eyes is the Confederacy). Because that's what America still is to it's core. It's still an incredibly racist nation held together by racist systems. A black man overtaking the senate in the favor of the Dems is what broke them.
I just hate pushing the idea that once Trump is gone "Trumpism" isnt going to be a thing. It's going to be a thing until we overthrow the system of racism that exist in America. Joe Biden isnt stopping Trumpism. America has to move towards true populism/socialism.
Oh no, Trumpism will still be there, I have no doubts. But I do think it's worth distinguishing as at least a subtype of nationalism.
A sort of nationalism that refuses to see anyone other than ones self as part of the nation.
Red's post was also pretty good, the complete disregard of any sort of 'expert' figure is built in as well and a key factor, though I don't fully understand how (the trope of only idiots being dumb enough to buy it doesn't fully explain it).
