When you deface a statue of Maimonides, it is about only one thing. Acting mayor Cintia Bustos ordered the municipal cleaning company Sadeco to send its stone-graffiti specialists first thing Monday morning. Maimonides, of all people, would have very little curiosity about one frightened man with a spray can. Seven hundred years before anyone coined the word “antisemitism,” Maimonides had already worked out where this particular hatred comes from. The first is the sword: outright killing, the method of Amalek and Sisera, and later Sennacherib, Nebuchadnezzar, Titus and Hadrian.
