Christan nationalism is cringed, but I would argue progressive internationalism of the DSA, and lefty people is also bad.
America is a pre-type one civilization, and unless we get taken advantage of, or close ourselves off to the rest of the world we will remain one until we become the type 1 civilization.
Eventually, the US will get Greenland to check Russia and China, and Canada to check a Chinese invasion of Russian Siberia if world events allow it. Moralistic garbage like being hypercritical is cringe. We should market ourselves as a moralistic country and often act that way, but the end goal isn't UNGA empowerment, it isn't lifting more people out of poverty, it should be a non-biased increase in aggregate power for the US first and foremost. We should act hypocritically when the cameras allow it. Fascists, libertarians, and progressives think too narrowly, and unrealistically.
Also, ethnic enclaves are horrible, we need more Americanization vs balkanization. The US shouldn't see Islamic patrols, Chinese police stations, and Russian spies run amok. I didn't grow up in Chinatown with a foreign police station, I wasn't that particularly interested in commie-based atheism( was agnostic), and I think spying for a future failed state is cringe.
Everyone can be an American of any race, religion, etc. Journalism is good for checking policy excess just don't leak state secrets like Snowden.
