It is not easy to yell "USA!" now that we are coming to grips with how big our problems are...
I've seen plenty of chanting and I'm sure the fans who traveled to London are not sitting in the stands saying "I just don't see how I can cheer this year."
We are acting like the failing superpower that we are.
If we are restricting this to cheering and displays of nationalism at the Olympics, it seems like excessive cheering is a sign of insecurity, not the other way around. I also don't think Fox made the case. I think the US uniforms represent the countries colors just fine. Serena Williams was very stylish in her blue USA outfit when she demonished Sharapova in the final. The women's gymnastic team was all red sparkles or blue sparkles when competing as a team. I heard lots of fans chanting at the beach volleyball matches. Do other countries chant at their athletes?
