You need to chill out and look at the future, not the past. If you dwell on the past, many countries have invaded many other countries. The British colonized and ruled the US for a long time. The US invaded Mexico and seized large portion of California and Texas. Even recently, the US invaded Yugoslavia, Iraq, Afghanistan, Syria, among others. China was the leading power for hundreds of years, way longer than the US or Britain. China rarely colonized other countries. The Chinese people look at the future, not the past.
"I have spent lots of time in China. They still want payback for the humiliation they believe they endured in the 1800s."
"What I was trying to say is that my opinion is not informed based on what I have read in the press but based on the fact that I have spent time in the country and have read the local press, and spoken with the local people. The humiliation faced by the Chinese at the hand of the western powers is a common theme of books and movies and TV shows in China."
When one is talking about Chinese territorial aggression and their desire to surpass the US as the geopolitical superpower, it is definitely not about the individual people.
Nothing the GGP said about the national Chinese interests was remotely controversial (perhaps subsequent comments are unrepresentative of individuals' thinking). Heck, Obama wanted to pass TPP mostly as a bulwark against Chinese ambitions.
