I think people are ignoring the sheer size of America, as other people have mentioned you can travel -IN- the country and see a much different place than you can in other places, but on top of that it's one hell of a lot harder to go somewhere else. Have any of you Europeans actually traveled to the U.S.? I've met plenty of well traveled Europeans who have been to just about every country in western Europe but maybe four or five who have been to the states. (Don't get me wrong, I'm not expecting any of you to come here. The only thing you might learn is how easy it is to get sucked into the fast food culture) but I was an army brat that spent large amounts of her childhood in other countries and when we were in Germany the same amount of planning went into flying to paris for a week as our vacation to Disney world ten years later, but going back home for Christmas was a year long planning event.
I don't agree with how a lot of Americans view the world, but I can kind of understand it.
