I wouldn't say I'm anti-anthem, but I don't really see it as necessary. But if you're going to do it, do it right. Sing the notes on the paper, not your personal jazzed up version. I'm also not a fan of the field-sized flags they use at football games, as they go against US Flag Code prohibition of displaying the flag horizontally. I'm kind of pedantic in that if you're going to do patriotism, do it right.
