In 1980. it was not the athletes who boycotted the Moscow Olympics.
In 1936, it was not the athletes who boycotted the Berlin Olympics.
Athletes are, on the whole, not terribly political people. Neither are musicians. Athletes are recognizant of the limitations of the human body and realize that at 20 to 24 they have their one chance at physical perfection in sports competition, and their body will never have that chance again. So in the pursuit of egotistical physical glory, some choose to ignore politics. Is this surprising? No. If I or you were in their shoes, most of us would be very annoyed with idiotic politics interfering with our personal ambitions, our personal moment of glory.
But is that to say that just because of that, politics don’t matter? Jesse Owens was a great man for showing up the myth of the Nazi “master race” and defeating them in the Olympics.
When will China realize that the world does not revolve around them? What does China have to offer the world beyond its huge size? Nothing. Japanese and Indian civilization have always been superior - everybody recognizes that. The only thing that China has ever offered in the past 2,000 years is that “Hey, we’re China, and we got a lot of people!” List one single innovation that China has made since the Ming Dynasty. Go on, I double, triple dare ya.
