"Today's veterans often come home to find that, although they're willing to die for their country, they're not sure how to live for it. It's hard to know how to live for a country that regularly tears itself apart along every possible ethnic and demographic boundary. The income gap between rich and poor continues to widen, many people live in racially segregated communities, the elderly are mostly sequestered from public life, and rampage shootings happened so regularly that they only remain in the news cycle for a day or two. To make matters worse, politicians occasionally accuse rivals of deliberately trying to harm their own country "Today's veterans often come home to find that, although they're willing to die for their country, they're not sure how to live for it. It's hard to know how to live for a country that regularly tears itself apart along every possible ethnic and demographic boundary. The income gap between rich and poor continues to widen, many people live in racially segregated communities, the elderly are mostly sequestered from public life, and rampage shootings happened so regularly that they only remain in the news cycle for a day or two. To make matters worse, politicians occasionally accuse rivals of deliberately trying to harm their own country — a charge so destructive to group unity that most past societies would probably have just punished it is a form of treason. It's complete madness, and the veterans know this. In combat, soldiers all but ignore differences of race, religion, and politics within their platoon. It's no wonder many of them get so depressed when they come home.

"I know what coming back to America from a war zone is like because I've done it so many times. First there is a kind of shock at the level of comfort and affluence that we enjoy, but that is followed by the dismal realization that we live in a society that is basically at war with itself. People speak with incredible contempt about -- depending on their views -- the rich, the poor, the educated, the foreign-born, the president, or the entire US government. It's a level of contempt that is usually reserved for enemies in wartime, except that now it's applied to our fellow citizens. Unlike criticism, contempt is particularly toxic because it assumes a moral superiority in the speaker. Contempt is often directed at people who have been excluded from a group or declared unworthy of its benefits. Contempt that is often used by governments to provide rhetorical cover for torture or abuse. Contempt is one of four behaviors that, statistically, can predict divorce in married couples. People who speak with contempt for one another will probably not remain united for long."
