I have seen many, many fine American athletes—as I am sure many on this thread have—standing at attention with quiet dignity, with tears rolling down their faces (the telephoto lenses obviously dismiss privacy) at this time.
Knowing who some of these athletes are, I know they are patriots indeed—
When you have winners on that platform who are clowning or fidgeting at the time a national anthem is played—whatever the nation—then that is bad and usually disgusting behavior.
The best moment of the olympics the last few years was Apolo Ono winning his first medal. The smug and cocky little boy stood on the podium getting his just reward. Then the national anthem rang out. His face contorted and tears welled up in his eyes. A boy became a man as he soak in the gravity of his victory. It was a beautiful moment.
