> Maybe Europe would benefit from having a bit more American-style "rah-rah" patriotism around the good old "12 stars on deep blue" EU flag.
Something most americans don't understand is how repulsive blatant patriotism is. A lot of europeans, along with their nationality, have a sense of being "european", just like most americans have a sense of being "american" (rather than just "Californian" or what have you).
There's nothing wrong with being proud of your country (or continent). There's everything wrong with an "in your face, my country is better than yours" attitude.
If you're a citizen of any EU country, you can just go anywhere else in Europe, no questions asked. You're welcome, anywhere in Europe. I travel a lot. I move a lot (I've lived in several different countries in the EU). This is one hell of a wonderful feeling; and even though, by distances, EU countries are similar to US states... there's really nothing like being immersed in a completely different environment. The weather is different, the language is different, the customs are different.
Singing the national anthem in schools? Chanting "<country>! <country>!" whenever something cool happens which you want to be a part of? It's alright I suppose when you aren't constantly crossing national borders. When there's only [edit: realistically] two other countries on your continent. Nobody's going to be offended (well, nobody that will be able to tell you). But it's the last thing Europe needs.
