The thing that bugs me about all these "If Europe, Then USA" articles is that they assume as their gospel truth that the starting conditions in Europe are exactly the same as the starting conditions in the USA and that both the New World and the Old World are monolithic, unchanging happy democracies going back to when we were pilgrims and knights respectively which was at some point so distant in the past that it just doesn't matter.
Look. Poland wasn't even a country except from 1918-1939 and 1989-now. It's been a baltic enclave of sophisticated culture and thinking, sure, but it's also been an uneducated hinterland with nobody to look out for it. When Italians adopted Tuscan as their national language in 1861, only 2.5% of the populace could speak it. Germany ceased to be "large chunks of Prussia" ten years after the American Civil War. There are ethnic and religious conflicts pock-marking European history going back to before the Greeks and Armenians battled over turf in 300 BC.
By contrast, America is pretty much "white people vs. everyone else" and even the white people haven't been here that long. It is a nation of immigrants and those immigrants have come in waves (by choice or by force) from four different continents. You can want your eggs and your potatoes not to touch on your plate, but not if you're eating a scramble.
American "ethic cleansing" looks like Trayvon Martin and Kaepernick on a Nike campaign. European "ethnic cleansing" looks like mass graves. It's shit like this:
And the Dreyfus Affair was incredibly important to the history of the Israel and European ethnocentrism but the modern American parallel is Trump Vs. Curiel.
Look. Europeans are racists, too. The preponderance of evidence and examples illustrates that Europeans are hella more racist and reactionary than Americans. And I recognize what an unpopular opinion that is to hold, considering we're the ones shooting black people in their apartments and locking up brown babies in cages but the fundamental difference is the Americans saying "Yeah! More brown babies in cages!" are now, have been and shall continue to be the lunatic fringe.
