I'm an American flag guy. I also enjoy hearing "The Star-Spangled Banner." I've presented history programs about its fascinating origin from the pen of Francis Scott Key. Those subjects are in the news right now because a San Francisco 49ers player has offended some Americans by not standing during the national anthem. He's protesting racial injustice in America by his shunning of the traditional stadium ritual and has defended his actions by saying he does not hate America as his critics have suggested.
