Enter any thread, on any major forum online, and bring up any of the following topics: healthcare, crime rates, gun control, two party systems, standard of living, inequality, conservative religiousness. You'll be rapidly overwhelmed by bragging from Europeans, about how they're superior.
You can't get away from the boastfulness out of Scandinavia, Germany, France, the UK, the Netherlands - about how they're all superior to America on any given topic. I've yet to find a major forum where this doesn't occur.
I disagree that patriotism or nationalistic bragging is in any way uncommon in Europe.
