Cardinal, while I like your analogy, I do think Schnitte has a point.
He doesn’t seem to get it across very well, so why don’t I give it a try - being European, and all-around swell guy that doesn’t wish any harm upon the United States. 
It’s not that people in Europe aren’t used to American patriotism. There’s a whole sociological debate we can have about a young nation, a nation seeking for an identity that describes the sum of its parts, a nation still eager to appear favourable compared to the Old World from whence their ancestors came: the fact of the matter is that in a lot of cases (bear in mind that a lot of the exposure Europeans have to Americans are either the “Ugly American Tourists” or tough talking politicians), Americans tend to come across with an attitude that says “bigger, better, more”.
And that’s all fine. It’s easy to shrug off: we all know that the shorts-and-Nikon-wearing pensioner from Austin, TX, visiting the red light district in Amsterdam isn’t a spokesman for all Americans when he says cars/roads/houses/food portions are bigger back home. Furthermore, most Europeans know damn well that the patriotic layer is thin, and that both sides of the pond have a lot in common upon further, more personal, investigation. And lord knows: each and every European counrty has their subset of Ugly Dutchmen/Frenchmen/Germans/etc. as well.
In short: while a minor annoyance at times, this is not what the fuss in this thread is about.
Ever since 9-11, the American Government has taken a complete hardline approach in the war against terror. While no one here is going to pretend there is nothing to combat against, I think it’s fair to say that the whole “You’re with us, or you’re against us” approach isn’t going over really well on this side of the pond. Part of it is the person George W. Bush: it’s no big secret that he is a lot less liked than his predecessor. Generally, people regard him as a tough-talking cowboy that fucks up a lot, and doesn’t seem to care a whole lot about cooperation with the rest of the Western world: the Kyoto treaty springs to mind. But then, in times of trouble, the same GWB tells the world that it’s “with them or against them”.
Of course, every single European country complied, because on humanitarian grounds alone, it was obvious which side was “right” in this war. But that doesn’t mean that the juxtaposition in American foreign policy is appreciated. In short: if you want the rest of the world to be on your side, you have to show your commitment the other way around as well. And that’s something that has been lacking under GWB, at least when one considers the general European outlook on it currently.
I hope I expressed myself clearly enough - I’m not looking for an all out US vs. Euro flame war here, and I understand the role patriotism plays when a country is under fire, so to speak. I’m just trying to shed some light on it from my side of the Atlantic.
