In Los Angeles, the recent riots have left several synagogues and Jewish-owned business looted or vandalized, including with such pointed slogans as “F— Israel” and “Free Palestine.” To find the real culprits behind such acts of violence, writes Cynthia Ozick, one must look to the intellectuals—and it has ever been thus:

The Inquisition was the brainchild not of illiterates, but of the most lettered and lofty prelates. Goebbels had a degree in philology. Hitler fancied himself a painter and doubtless knew something of Dürer and da Vinci. . . . The hounding and ultimate expulsion of Jewish students from German universities was abetted by the violence of their Aryan classmates, but it was the rectors who decreed that only full-blooded Germans could occupy the front seats. Martin Heidegger, the celebrated philosopher of being and nonbeing, was quick to join the Nazi party, and as himself a rector promptly oversaw the summary ejection of Jewish colleagues. Stupid mobs are spurred by clever goaders: the book burners were inspired by the temperamentally bookish—who else could know which books to burn?

Anti-Semitism dressed in the sheep’s clothing of social justice is the province of elevated pitchmen—cultivated elites, learned professors, scholarly theorists.

At the heart of the dangerous theories of today, writes Ozick, is the doctrine of “intersectionality,” according to which various groups of people are ranked so that the most oppressed are categorized as the most righteous:

On the lowest rung of [intersectionality’s] hierarchy of ethnic worthiness, Jews are designated as white oppressors of marginal peoples. They are accused of complicity in a colonialist plot against Palestinians and as accomplices in the training of police brutality. If they profess to be liberals, or radicals of the left, they are shunted aside as persecutors of the weak. Even as they are scorned as unfairly privileged, they are treated as campus pariahs.

Marxism is a movement of the deluded; anti-Semitism is a movement of the cleverest. When students become inquisitors and administrations are feeble, when the elect succumb to the political haters, so will a nation’s conscience. A vengeful mob is a fearsome thing, but the true monsters are its teachers.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
