I know how Venn diagrams work buddy. I’m pointing out the lack of logic in your argument. Populism and nationalism don’t have much to do with fascism which is a product of liberalism and capitalism. There are plenty of examples where nationalism and populism result in socialist movements, Viet Cong being one prominent example.
This is to say that you don’t actually understand the cause of fascism and its relationship with populism and nationalism.
I can’t believe I have to explain this to someone but here we are.
