People in Europe know all the big American cities and are well aware of the political differences. If someone asks where you are from, don't tell them you are from the US, tell them you are from NY/Chicago/LA/SF/whatever. There is a pretty decent chance that it will lead to a nice friendly conversation that you'll never get with an "I'm from the US" answer.
