The gravity of Jewish suffering over the ages, culminating in the Holocaust, makes it almost impossible to entertain any suggestion that Jews might have brought their troubles upon themselves. This is, however, in a rather narrow sense, the truth. Prior to the rise of the church, Jews became the objects of suspicion and occasional persecution for their refusal to assimilate, for the insularity and professed superiority of their religious culture—that is, for the content of their own unreasonable, sectarian beliefs. The dogma of a "chosen people," while at least implicit in most faiths, achieved a stridence in Judaism that was unknown in the ancient world. Among cultures that worshiped a plurality of Gods, the later monotheism of the Jews proved indigestible. And while their explicit demonization as a people required the mad work of the Christian church, the ideology of Judaism remains a lightning rod for intolerance to this day.
