Me neither. In fact, I don't understand how you can be proud on something so antiquated like the concept of a "country". Wooo, I was born somewhere, and now everyone who was born near me call me their countryman. Hooray! I haven't done anything to be born there, but I am nevertheless so proud to be a fellow countryman, yipee! And you, who was born over there, go fuck yourself, you dirty foreign bastard.
You only think this way because of very recent developments like television, telephone, radio, the airplane, and most importantly the internet. Before that, your world was basically restricted to your family, your neighborhood, your city, your country, in that order. That's not even going into man's collective instinct that has been reinforced for thousands of years in pack based hierarchies. Why? Because it worked. If they existed and propagated, it is because they were more effective than their counterparts, in a purely darwinian sense.
The crazy technological progression as far as as distribution of information goes in the last 100 years alone is fucking mindblowing. We're still trying to deal with it with all the lizard brain instinctive baggage that makes humans...humans. Physically, instinctually, emotionally we're no different from any other homo sapiens that has existed for hundreds of thousands of years. Instead of looking down on them as backwards retarded apes that just didn't know better, we should be trying to understand the mechanisms that drove them to addopt those forms of socialization. They're basically us, under different circumstances, as far back as recorded history goes, and much further.
