I wasn't aware of that, but you're reacting as a stickler for historicity here and are sort of missing the point, aren't you? Yes, a pox on both houses in some sense, but progressives are still inclined to root for the underdog, and the David and Goliath story is a paradigmatic expression of that impulse. So who's David in the Arab-Israeli conflict? The answer turns out to be paradoxical, as I argue, and that's so regardless of whether the Bible is full of myths.
