On a tangential note, watching the documentary on her was the first time I viscerally understood that people with very different ideas about how to live can agree on some fundamental political principles, and don't have to stuff themselves into right/left boxes for easy manipulation. They went after her hard because a culturally-conservative, intelligent, hard-nosed soldier type who sticks to virtues that are not completely in-line with our warhawk doctrine is their worst nightmare.
