Why do Americans lack humility?

Anonymous
German and Japanese people showed great humility after losing WW2. Granted many individuals didn't not show remorse for their atrocities, but the people overall did.

But in America, you'll find marginally more Nazi sympathizers than in Germany, and somehow a move to take down a Confederate statue led a protest where they chanted "Jews will not replace us" in defense of it. I get the feeling that Americans just love being angry whether it be PC SJW's or people who just are Anti-PC SJW's
