JONAH GOLDBERG: The right’s antisemitism problem is well known. What about the left’s?

The good news is the bad news is wrong. The bad news? Harvard-Harris poll which found that 67 percent of 18- to 24-year-olds believe that “Jews as a class are oppressors and should be treated as oppressors.”

One piece of good news: The poll is pretty lousy, as Ilya Somin, author of “Democracy and Political Ignorance,” explained for Reason magazine. The poll combines two questions in one, asking people to agree to both the description of “Jews as a class” and how they should be treated and uses terms such as “oppressor” that are fairly unfamiliar to people not plugged into campus-speak.

Even better news: the poll is an outlier. Surveys from respected outfits such as the Pew Research Center find that American attitudes toward Jews are pretty favorable.

But this is where the supply of good news runs dry. Because even if Harvard’s findings exaggerate the problem, the problem still exists. Actually, there are several problems: rising antisemitism in the United States, particularly among young people and, not unrelatedly, a depressing amount of both general ignorance and highly cultivated ignorance.

Given the horrific headlines since the Hamas attack, it’s not worth rehashing the evidence of antisemitism’s resurgence, both on college campuses and off. In October, FBI Director Christopher Wray testified that antisemitism was reaching historic levels, with fully 60 percent of religious hate crimes being committed against 2.4 percent of the population.

As for general ignorance, a Economist/YouGov poll finds that one in five 18-29-year-olds believes the Holocaust is a myth. Another 30 percent said they don’t know if it is. One way to look at this is to just throw this on the pile with other depressing findings of widespread ignorance about things that have nothing to do with Jews. Half of Americans cannot name the three branches of the U.S. government.

Social media surely plays a big role. While it’s true that bad actors, at home and abroad, have been pumping antisemitic sewage onto kids’ screens for a while now, it’s worth keeping in mind that digital iconoclasm — tearing down any established truths — and conspiratorialism are rampant on the internet (a quarter of Europeans, and twice as many Russians, think the moon landing was faked. Nearly a fifth of young Americans agree).

Still, the Economist found that most older Americans know the Holocaust happened. In other words, young people are a particular problem.

Which brings us to the cultivated ignorance, i.e. the deliberate encouragement of anti-Jewish bigotry by various institutions and “influencers.”

The right has a well-publicized antisemitism problem. The GOP frontrunner famously dined with antisemites Kanye West and Nick Fuentes. Various new right and alt-right gargoyles indulge anti-Jewish and anti-Israel rhetoric from their internet perches.

That’s all grotesque, but those gargoyles don’t control the commanding heights of the culture the way the left does. The power of left-aligned academics and activists shouldn’t be underestimated. While groups such as the Anti-Defamation League, Southern Poverty Law Center and the various elite media outlets that rely on them as authoritative sources have covered right-wing antisemitism zealously, they have allowed the intellectual poison of anti-colonial and anti-oppressor ideology to go unchecked.

This ideology takes it as a given that Jews, Zionists, Israelis — pick your label — are indeed “oppressors.” This framing is seductive to young people who want to belong to a righteous, rebellious cause more than master basic facts.

For instance, University of California-Berkeley political scientist Ron Hassner recently conducted a small survey of college students on issues related to Israel. Most students (86 percent) supported the popular chant “from the river to the sea, Palestine will be free.” But nearly half (47 percent) couldn’t name the river or the sea in the chant. Some guessed that the river was the Nile or Euphrates and that the sea was the Atlantic or Caribbean. Ten percent thought Yassir Arafat was the first prime minister of Israel.

The shock of decent liberals and progressives at the explosion of antisemitism in the wake of the Hamas attack is testament to the delinquency of the left-wing elites running academic and cultural institutions. When professors and students celebrate a pogrom and administrators find themselves tongue-tied about condemning murder or the harassment of Jews on their own campuses, the complacency becomes obvious.

One last piece of good news: When Hassner’s researchers explained basic facts to the students who enthusiastically embraced “from the river to the sea,” many of them changed their views. Yes, this survey illustrates the failures of the center-left. It also shows they can remedy them — if they want to.
