user1+1=5 No such delusion here, when I go off into the world I am definitely European first, British second, if they care at all about the latter. Who sees your passport apart from immigration officers? And if I go to the US half the time they think you are Australian.
Do you, I wonder, distinguish between Korean (let alone South and North) Chinese, Vietnamese, Cambodian, Laoatian, Malaysian, Singaporean?
