You believe every one of us in the military are incompetant, amoral tyrants bent on making the US unlivable.
What the poll tells me is that there are many people who understand that everybody in the military cannot be judged by the actions of a few that were put in extremely unusual conditions (and may or may not have been ordered to do what they did). The poll tells me that many still know that we are trying our best to improve the world that we live in even though we sometimes make mistakes. They know that only our mistakes make the news, the good that we do seldom does, and when it does, it's not Headline news. But they know that their sons and daughters are doing more good than bad.
Just because the poll doesn't fit with your opinion, doesn't make it wrong. Nor does it show a country that is collapsing. It shows a country that despite some dissidents, is holding together fairly well.
But don't worry, we'll continue to fight for your right to be an idiot
