How to tell you're an American even when you're not talking too loud or wearing running shoes at the airport

Plenty of times I've wanted to hide my US passport when I'm traveling around the globe. There was that year W won the election and the whole city of Stockholm had to know why I elected him. And as global anti-American sentiment has raged on, I frequently want to make like those dudes on the subway who slip their porn inside a Time magazine. So I get the idea of hiding the old blue in an anonymous holder. But can someone please explain why you would want to pay two hundred bucks for the Smythson passport holder that boldly proclaims your citizenship?
