Most of the arguments on the left in favor of Hamas center on the notion of historical context within a framework of injustice. In other words, no matter how heinous the response is to the perceived injustice, it is justified by the context. I think that it is fair to say that both Hamas and Isis celebrate violence as art form; they have this in common with the Vikings of the ninth century and the Mongol hordes of the thirteenth. Unfortunately, this is utterly incompatible with any notions of civilized behavior as we understand them. You cannot call for a ceasefire on the one hand and not denounce institutional rape and the murder of children as a mere side effect of conflict. To be clear, this latest conflict was started by Hamas. In my opinion, the left is doing itself a great disservice by trying to cloak unacceptable behavior behind their cowardly response to October 6th.
