Well, let's count how many people the USA killed with 2 wars in Irak, one in Afghanistan, one in Vietnam and countless operations in South America. Or how they mostly put non white people in a privatized prison system that then exploit them. Or how their police is so peaceful and close to the population the entire country had a debate about de-funding it.

Sure, China is worse, but it does make a useful mirror. Like Russia was a useful one during the cold war.
