For decades after the Holocaust, antisemitism occupied a uniquely shameful place in Western public life. Open hostility toward Jews was politically toxic. Universities, media institutions, and activist movements treated antisemitism as a moral taboo — a warning from history about how civilized societies could descend into hatred.

That consensus has fractured.

In the aftermath of October 7, Jewish students reported harassment on elite campuses. Anti-Israel protests frequently crossed into openly anti-Jewish rhetoric. Slogans once considered extremist entered mainstream activist spaces. In many progressive circles, hostility toward Zionism became socially rewarded, while concern about antisemitism was increasingly dismissed as reactionary, manipulative, or politically inconvenient.

How did this happen?

The answer did not begin in 2023. It has roots stretching back more than 150 years.

A growing number of historians argue that modern left-wing antisemitism evolved through a long ideological transformation — from Karl Marx’s writings on Judaism, through Soviet anti-Zionist campaigns, to the New Left’s reframing of Jews as symbols of “privilege,” “colonialism,” and “oppression.”

One of the most detailed recent examinations of this history appears in The History of Left-Wing Antisemitism: How Progressive Ideology Turned on the Jews, from Marx to October 7.

Why Antisemitism Became Socially Acceptable Again

Modern antisemitism rarely looks like the crude racial hatred of the 1930s. Instead, it often arrives wrapped in the language of social justice, anti-colonialism, or anti-capitalism.

That transformation matters.

Historically, antisemitism adapted itself to the dominant political language of each era:

Medieval Europe accused Jews of religious corruption.
Nineteenth-century nationalists accused Jews of racial contamination.
Twentieth-century fascists accused Jews of global conspiracy.
Modern ideological movements increasingly portray Jews as embodiments of systemic power.

This newer form often avoids explicit references to Jews as an ethnic or religious group. Instead, Jewish identity becomes indirectly targeted through attacks on “Zionists,” “global elites,” “colonizers,” or “financial power.”

Critics argue this rhetorical shift allows antisemitism to re-enter respectable discourse while preserving plausible deniability.

The Origins: Marx, Socialism, and the “Jewish Question”

Many people are surprised to learn that hostility toward Jews appeared within parts of the early socialist tradition.

Karl Marx’s 1844 essay On the Jewish Question described Judaism in deeply negative economic and cultural terms, associating Jewish identity with money, commerce, and capitalism. Historians continue debating how literally Marx intended these passages, but the rhetoric itself became influential.

Later socialist movements often framed Jews as symbols of financial exploitation, bourgeois decadence, or capitalist corruption.

By the late nineteenth century:

European labor movements sometimes excluded Jewish workers.
Socialist publications caricatured Jewish bankers and merchants.
Revolutionary rhetoric increasingly merged anti-capitalism with anti-Jewish stereotypes.

This ideological fusion became even more dangerous in the Soviet era.

Soviet Anti-Zionism and State-Sponsored Antisemitism

The Soviet Union officially condemned antisemitism. In practice, however, Stalinist campaigns frequently targeted Jews under political labels.

During the “anti-cosmopolitan” purges of the late 1940s and early 1950s:

Jewish intellectuals were arrested or executed.
Jewish institutions were dismantled.
“Rootless cosmopolitans” became coded language for Jews.
Zionism was portrayed as a global threat linked to Western imperialism.

The Soviet Union later exported this anti-Zionist framework across the global Left during the Cold War.

By the 1960s and 1970s, Soviet propaganda increasingly depicted Israel not as a small Jewish state surrounded by hostile neighbors, but as a racist colonial project aligned with capitalism and American power.

That reframing profoundly influenced universities, activist organizations, and international institutions.

How the New Left Recast Jews as “Oppressors”

After World War II, Jews in the West achieved unprecedented social mobility and integration. Ironically, this success altered how many activists perceived Jewish communities.

In newer ideological frameworks centered on power hierarchies, Jews were increasingly categorized not as a vulnerable minority but as beneficiaries of “whiteness,” privilege, and institutional influence.

This shift created several consequences:

1. Jewish Victimhood Became Politically Inconvenient

Progressive movements often prioritize narratives of oppression based on race, colonial history, and power structures. Jews did not fit neatly into these frameworks.

2. Israel Became a Symbolic Villain

Israel increasingly functioned as a symbolic stand-in for Western colonialism, capitalism, militarism, and nationalism.

3. Antisemitism Was Reinterpreted as Secondary

In some activist spaces, antisemitism came to be viewed as less urgent than racism, Islamophobia, or colonial oppression — despite rising anti-Jewish incidents globally.

The result was a climate where rhetoric once considered antisemitic became normalized if framed as “anti-Zionist.”

October 7 and the Collapse of the Post-Holocaust Consensus

The Hamas attacks on Israel on October 7 marked a turning point for many Jews worldwide.

Instead of universal condemnation, some activist groups immediately justified or celebrated the attacks as “resistance.” Jewish students reported intimidation on campuses. Demonstrations featured slogans widely interpreted as calls for Israel’s destruction.

For many observers, this moment revealed how deeply anti-Israel ideology had merged with broader hostility toward Jews.

The controversy reignited interest in the historical roots of left-wing antisemitism — and why so many intellectuals failed to recognize it developing in plain sight.

Why This History Matters

Understanding the history of left-wing antisemitism is not about condemning liberalism, socialism, or criticism of Israeli policy.

Legitimate criticism of governments is normal in democratic societies.

The issue arises when:

Jews are collectively blamed for political systems,
Jewish self-determination is treated as uniquely illegitimate,
anti-Jewish tropes are recycled under ideological language,
or violence against Jews becomes morally excusable when framed as revolutionary politics.

History shows that antisemitism rarely disappears permanently. It evolves.

That evolution — from Marxist rhetoric to Soviet propaganda to modern activist discourse — is the focus of The History of Left-Wing Antisemitism.

FAQ: How Antisemitism Became Fashionable

What is left-wing antisemitism?

Left-wing antisemitism refers to hostility toward Jews emerging from socialist, progressive, anti-capitalist, or anti-colonial ideological movements. It often frames Jews as symbols of power, capitalism, privilege, or oppression rather than focusing on racial theories traditionally associated with the far Right.

Did Karl Marx write antisemitic material?

Yes. In On the Jewish Question, Marx used language associating Judaism with money, commerce, and capitalism. Historians debate the meaning and context of the essay, but the text contains rhetoric widely viewed today as antisemitic.

How did the Soviet Union spread anti-Zionism?

The Soviet Union promoted anti-Zionist propaganda throughout the Cold War, portraying Israel as a colonial and racist state aligned with Western imperialism. These narratives influenced universities, activist groups, and international political movements worldwide.

Is anti-Zionism the same as antisemitism?

Not always. Criticism of Israeli government policies is not inherently antisemitic. However, anti-Zionism can become antisemitic when it denies Jews alone the right to national self-determination, uses anti-Jewish stereotypes, or holds Jews collectively responsible for Israel’s actions.

Why do some progressives view Jews as privileged?

In certain ideological frameworks emphasizing racial and power hierarchies, Jews are often categorized as socially successful or “white-adjacent,” causing some activists to overlook Jewish vulnerability and antisemitism.

Why did October 7 change public debate about antisemitism?

The reactions following October 7 shocked many observers because some activist organizations appeared to justify or celebrate violence against Israeli civilians. This intensified public discussion about whether anti-Israel rhetoric had normalized hostility toward Jews more broadly.
