Will they say that it is Israel’s disproportion in force that is shocking, the imbalance between an all-powerful army and defenseless civilians? That argument has some merit, but in the end it also doesn’t hold up. For if that were the reason for protests—if one were primarily concerned about the Palestinian children whose deaths are indeed an abomination—one would demand that Hamas operatives leave the hospital basements where they have buried their command centers, move the rocket launchers that they have installed in the doorways of United Nations schools, and stop threatening parents who wish to evacuate their homes when an Israeli leaflet informs them that a strike is imminent.

Moreover, if alarm about disproportion and asymmetry were the true wellspring of the protesters’ rage, would they not have had at least a passing thought for another disproportion that, not so far from Gaza, now afflicts the most wretched of the wretched, the most defenseless of all, the Christians of Mosul? Hamas’s “brothers” are offering these Iraqis the following ultimatum: Embrace Islam or die by the sword.

The truth is that these protesters—most of them young members of the self-proclaimed “Gaza generation,” for whom the latest in chic is to sport a kaffiyeh made in Palestine—assume it is normal for Arabs to kill other Arabs.
