It's not the most offensive thing I've ever read, here or there, but also the source: I would have expected a little more from you. It seems ill-considered.

You feel that your moral paradigm, militant western democracy, is greater than the Taliban's moral paradigm, militant Islamic theology. Well, that's fine: I actually agree with that. But there's a reason that human beings have come up with certain codes of conduct, for instance, the Geneva Convention, to codify the operations of war. Within that codification, to which our military subscribes, we recognize the inherent immorality of the desecration of dead human bodies. We say it's an immoral thing to do, whether it's done by our enemies or done by our own soliders, and we recognize that certain acts go above the finger pointing of "this side is worst than that side", and are inherently, universally "wrong". You're shrugging that off and saying that this immoral act is okay, because those other guys are so immoral, which unravels the whole ball of string. If the Taliban were pissing on the flag-draped bodies of dead marines, you'd very likely be upset. I find either circumstance incredibly disturbing and base, and "wrong".

(If you come up with something interesting in response, I might reply. Ad hom and I'm all set, as I'm reading Sex at Dawn and it's super engaging.)
