@truthbknown: "Here's the biggest issue of all (not that any of this really matters) - Why would we want out national anthem played at the beginning of a sporting event?"
I am with you on that. I have a theory: inculcating patriotism is no different from indoctrination in a cult. Hence the repetitions as much as possible, even in events (football games) where Americans beat...yes, beat other Americans, not the enemy. And quite commonly the players thank God for the victory. We are surrounded by cults.
Instead of so much emotional indoctrination through pledges and anthems, we should do a better job at teaching U.S. history and World history. That will give plenty more reasons to want to be an American. I just sang the U.S. National Anthem in the ceremony of my naturalization as a U.S. citizen. The Anthem and Pledge of Allegiance played no role in my desire to be a U.S. citizen; my knowing U.S. history and having lived in the U.S. for many years did.
