What could this mean? I'm not sure I get it
At the same time, however, European identity is externally exclusive – that is, it excludes those who are not European or cannot think of themselves as being European.
I moved to EU to live from non EU, I could think of myself as European, or I could not (depends), but does that mean I cannot be European? Why not?
If I cannot think of myself European, how could I identify as being one. It's how you identify...
"Who are you?.. identify yourself at once!" - now how I answer this I could make me either Euro or not.
IMHO a bit of salt from UK way...
