Agreed, the US definitely needs to do some introspection to sort out its own shit (and stop spraying it on everyone else).
However, that does not mean that China gets a pass. Fundamentally, the Chinese model of governance does not protect the individual. For all its faults, the US model is based upon the idea of individual liberty, which acts as a touchstone and allows it to self-correct whenever it goes to far in the wrong direction. That's something the Chinese model does not do, and means that, short of a revolution, it will continue to be an authoritarian state with all of the malignant features that entails.
