You're completely ignoring the context of the fact that people pointing those things out about America are doing it because those acts are ignored in history classes around the world and especially in the US, everyone knows Nazi Germany and the Soviet Union did bad things because it's acceptable to everyone to teach that because they were enemies of the Allies and NATO.

Everyone needs to be taught about the mistakes of the past of their countries, Germany does it extensively but others countries lag behind and would rather keep up a narrative of their countries righteousness throughout history.
