> I don't know anything about war, but even I know that it's utterly naive to expect that soldiers wouldn't get off on killing people. It is completely to be expected. How far are you willing to take this argument? Statistically speaking, it's to be expected that invading armies will rape a substantial portion of the female population. Would it therefore be "prissy" to be outraged if this happens? >This is part of th…
The difference is that we ask soldiers to kill people, we don't ask them to rape them. To ask, pay, and celebrate them for doing the former and then fastidiously insist that they only do it in a way that conforms to our hero fantasies is incongruent. That being said, it is naive to unleash violence and not expect it to spill over. So I guess in the case of war rape I would say that while it's not prissy to be outrage…
Well, it would be incongruent to do that, yes, but I don't ask them or pay them or celebrate them.
I expect the soldiers in the video are just doing what a lot of people would do in the same situation. That might make their behavior in some sense "normal", but it doesn't make it OK, or beyond reasonable criticism.
Most of what you're saying could equally well be applied to (e.g.) criticism of suicide bombers. It may well be the case that suicide bombers are not, as a rule, unusually evil people. If you have the relevant life experiences, you might even have a sense that you'd do the same thing if you were in their position -- in the same way that it's easy for an American to feel some sympathy for the soldiers in this video. Nonetheless, the actions of suicide bombers are unambiguously wrong, and are rightly subject to criticism.
(Of course, I'm not attempting to equate the soldiers' actions with suicide bombing, it's just an analogy.)
