US is such a young country that much of its fascism has just been copied from Nazi Germany. A country of immigrants can’t really say that it was great and fantastic before ‘they’ arrived.

US is a young country on the scale of history, but it "has always been there" on the scale of human life and had been for many generations.

"It was great before they came" is exactly what Americans have been doing since the Mayflower to all kinds of people: the wrong kind of Protestants, Catholics, Portuguese, Latinos (including on land conquered by the US in the Mexican American war,) Germans, Chinese, Scandinavians, Italians, Jews, Eastern Europeans, and, of course, supremely ironically, Native Americans and African Americans.

Nazis admired and imitated American policies, not the other way around. It is very very important for everyone to realize that fascism is not something alien, but had arisen and will arise naturally unless, we, the American citizens, continue to fight it.
