This is interesting to me. As an American, our national identity certainly looks similar; it's composed of favorite pastimes and products and shared political values.
But is that true in Europe? The cultures of European countries are much older, predating capitalism and the democratic governments they have today. Most of them are more or less homogenous, whereas the US has always been a nation of immigrants, and the whole "melting pot" idea has been around for most of our history, even if our behavior and policies sometimes clash with it.
Also, I'd argue some of the nation states in Europe are invented, like Italy and Germany, which each were basically just a bunch of city states that were more or less force ably amalgamated into one country. I don't know much about modern German or Italian nationalism, but I think that might have a negative impact on an overall European identity.
Granted, I'm speculating here. At the end of the day I'm an American who doesn't know what he's talking about. Though I do think it's telling that a good number of things you offered as components of a shared European identity were invented in America.
> There's a reason why Europe is many times referred as a whole. "They do it like this in Europe", "In Europe they prefer that" (and it's not always ignorance ;)).
Do actual Europeans say that? Sounds more like the typical American who just got back from a vacation in Europe.
