I'm not a big fan of patriotism in general, but something I noticed about the US patriotism is the tendency to call the US "the best country in the world". This crosses all political differences, e.g. I recall being surprised how Michael Moore was saying it in an interview or movie (when justifying criticising policy, he said he does it because he knows that America is the best country in the world). Even the most patriotic friends I have in other countries would typically not say this.
