Because when your enemy commits a crime against you, and a heinous, immoral one at that, how is it NOT yours to judge? As I said, this refusal to judge isn't the mark of moral refinement, it is moral cowardice and cheap relativism. And it makes it easier for our enemies to continue to commit such crimes when they are not held accountable. You would take offense, I suspect, if someone were to question which side you are on in this conflict. And yet, you won't even act like you really are on our side on an issue where there isn't even any ambiguity. That is, in a word, wrong.
