Look, I am well enough aware of the depth of the crimes and misdeeds of US imperialism. I'm not blind. But the current Chinese regime has many repressive aspects, different and often more grave than those we find in the US. Also, if one examines its history, the number of internal deaths arguably caused by government malfeasance is much greater in China than in the US. So while I may agree with your bottom line, a person weighing the failings of the US and China may argue that "China is worse", and that would not be a preposterous claim even if we disagree with it.
