As an American who is critical of American society on some fundamental issues that go beyond the particular party in power, I have had somewhat similar experiences. You can't knock the system or The Way Of Life. However, there is also a particular strain of xenophobia that describes your experience.

European sites to me are something more than bring just non-US sites. By their nature they are compelled to be international sites. I can't think of much on which Europeans stand united. What I seek is an opportunity to escape the claustrophobia of any body's nationalism.
