The original post didn't mention the US.

My response didn't say any country was better or worse than any other country, just that China had an imperialist past.

The strange whataboutism you're doing and trying to "debate" things that only you have brought up isn't a compelling form of argumentation. Stating that I was defending and spewing "apologist nonsense" about the US, when I hadn't mentioned the US at all is just really odd. I can't tell if you're really young and haven't learned about how to argue points and/or you're from China and simply can't handle anything negative said about your homeland?
