I have to admit that any contest on “patriotism” I would lose. I do believe in duty to country… but I see citizenship more in terms of pragmatism than pride (being a citizen of no nation is simply not a practical option). Still, the reactions over that commercial from Coca-Cola was weird. The fact that it is often the newbies (new citizens) that have greater patriotism or love of country than the old-timers (citizen by choice rather than by chance) should make one question the strange reactions to the ad. I am a US citizen only, while my wife and children are dual citizens (citizens of the US and the Philippines). I have seen stuff on the Internet of people who fear that dual citizenship is un-American and opens the door to terrorism and other things. Hardly likely. My wife speaks four languages fluently (as opposed to me who speaks 1 to maybe 1.3 languages). Can’t see how language says anything about patriotism.
For me, however, in the end, showing off how patriotic or nationalistic one is is a bit of a waste of time for Christians. Christians are dual citizens (heaven and earth). Since citizenship in heaven overflows any national boundaries, I HOPE that the over-the-top reactions did not come from Christians. But Christians lose perspective as fast as anyone else, sadly.
