An American soldier goes missing, turns up as a prisoner in a Taliban propaganda video. Then Fox News "analyst" Ralph Peters publicly states that the soldier is probably a deserter, and "the Taliban can save us a lot of legal hassles and legal bills." Here's Rachel Maddow discussing the situation.
As far as anyone can tell, Ralph Peters' "source" is his butt, from which he pulled this "inside" information that the soldier abandoned his unit.
Why go to all this trouble to slander a captured soldier? What's the point? Personally, I think it's because Peters' form of conservatism shares qualities with karma and "The Secret." On a basic level, it is the belief that everyone deserves what they get. Are you poor? It's because you did something bad in another life. Got cancer? It's because you "wanted" cancer. Are you a prisoner of a murderous dictatorship in a foreign country? Well, I don't know exactly what you did, but somehow you must deserve it.
I suspect that people such as the odious Michelle Malkin are willing to believe Peters because it makes them feel better. It's very sad if a soldier is in enemy hands and possibly facing execution. But if you can convince yourself that he OUGHT to be executed, well then, problem solved.
