I think the anti immigration right wing rise across several European countries rn shows that they've just never had the dialogue that the US does about race from being such a melting pot, and as such have ignored racial issues and racism in their societies bc they haven't had as terrible of a racist past as the US (Jim Crow laws, neoslavery, etc) that they have to confront. Now that the globalized world is causing more demographic change in Europe there's a loooot more anti-immigration and racist rhetoric. That's not a coincidence.
