You are not criticizing the county, you are typecasting and criticizing the people of that country. And you are criticizing them because they are Chinese. Your comment was aimed at all Chinese citizens in China, typecasting them as all behaving in the same derogatory fashion, because they are Chinese. You obviously consider all Chinese citizens in China as inhumane murderers who put their own interests above the sanctity of a human life. Really? Every person in China would kill an innocent victim by running over them again and again to make sure they are dead? Exactly what is that supposed to say about a Chinese person? Your comment was nothing more than a typical racist joke. Does your racist 'joke' have anything to do with your display moniker?
Yes I would also call someone an anti-Semite who says 'All Jews want to exterminate the Palestinians just because Jews hate Palestinians' just as I would call an Israeli or anyone else racist for saying 'The only good Palestinian is a dead Palestinian'.
