I do not dispute that all countries have dark parts of their history. The U.S. is obviously no exception, however, your original claim was that what goes on in China the past 50 years has worked well for it's people... Yes and no. Yes, China has raised more people out of poverty in that period of time than any other country in history ( although the per capita GDP is still far below that of the U.S). No, the uighur muslims are currently being the subject of crimes against humanity in the form of forced incarceration, sterilization and labor. Yes, China is has complicated history as does the U.S., but there is no shame in someone passing judgment on human rights violations such as repression of speech or control of media, whether it is the U.S., China, or elsewhere. So, I disagree with your original claim that the U.S. should stop passing judgment, but I agree that there is plenty of blame to go around. The only solid ground to stand on that I can see is calling out bad behavior wherever it is found and then engaging in discussion. I appreciate the back and forth. Hope all is well where you are. Best,
