Because we are not just a collection of autonomous individuals bumping into each other with social Brownian motion. We are a *country* - a national community - a *society.* I would think on September 11, on this day of all days, we would understand and appreciate the virtue of *patriotism.*
God created all people in His image, but some people have a greater claim on our allegiance than others. First there's our family, then our neighborhood, our city, then our state, and ultimately our nation. If we don't have a nation and a national consciousness, ultimately dead-end jobs for virtually everyone will be the *least* of our problems. You can't protect from invasion that which you do not value. Ask the Romans in the late fifth century AD.
Excellent post!
