The Digital War Against the Jewish Community Is Raging, Perhaps Worse Than Ever

On Monday, the remains of Ran Gvili — a young Israeli police officer killed during the October 7, 2023, Hamas attacks — were finally recovered from a cemetery in northern Gaza. With his return, the hostage crisis effectively came to an end. There are no more Israeli hostages in Gaza.

This final milestone received far less international media coverage than the release of the last living hostages in October 2025, an event that had a noticeable impact on the digital landscape. As we found in a student-driven project at the Social Media & Hate Research Lab at Indiana University’s Institute for the Study of Contemporary Antisemitism, antisemitism dipped on X and TikTok the day those living hostages were released. But the respite was short-lived.

Social media has become a toxic environment for Jews. The sheer volume of hateful commentary on anything Jewish — from current events to the Holocaust — is staggering. But to view these platforms as merely “loud” is to miss the more dangerous reality: social media is today’s primary tool for disseminating antisemitism and, increasingly, for mobilizing it.

Our research shows that social media is being used to politicize antisemitism and coordinate action across ideological boundaries. What often appears as a spontaneous burst of passion — such as student activism on campus — is frequently the result of a highly networked digital infrastructure.

In our lab’s study on the “Rhetoric of Resistance,” we tracked the online networking of anti-Israel campus groups across the United States. The findings are a wake-up call for university administrators and policymakers: these groups are not operating in isolation. They have built a wide network of off-campus organizations and individuals, allowing them to synchronize messaging and amplify radicalized narratives at an unprecedented scale.

We are seeing a shift toward language that mirrors the rhetoric of designated terrorist organizations. Slogans that deny a people’s right to exist or that justify violence are no longer fringe; they have been moved into the mainstream of campus discourse through coordinated digital amplification, often expressed in snippets, coded phrases such as talk about “Jewish power,” “Zionist evilness,” or even slogans such as “Free Palestine,” which has become a battle cry.

One of the most troubling patterns our student coders identified is how specific types of political commentary function as “gateways.” While many users believe they are simply criticizing a government’s policy, our data shows that totalizing, categorical condemnations — framing an entire nation as “genocidal” or a “terrorist state” — are most strongly associated with antisemitism. In contrast, humanitarian-focused themes, such as the suffering of individual Palestinians, showed a much less consistent association with anti-Jewish hate speech.

Our central finding is nuanced and confirms other studies: negative views of Israel and antisemitism are strongly correlated. Approximately half of the posts we analyzed that expressed negative views of Israel were antisemitic, while posts with positive views showed zero antisemitism. The students’ diligent coding work allows us to demonstrate empirically how criticism can create a permissive environment for antisemitism without every post necessarily crossing the line into hate speech.

However, in the vast majority of the most vitriolic posts, the content was not just “anti-Israel”; it was fundamentally anti-Jewish, utilizing collective blame and dehumanizing language. This creates a “permissive environment” where hate speech is sanitized as political advocacy, making it difficult for platforms — and even trained human moderators — to draw the line.

The one-day dip in antisemitism we observed during the 2025 hostage release proves that the digital climate is sensitive to reality and human empathy. However, the immediate “snap-back” to hostility suggests that the underlying machinery of mobilization is always running.

If we are to protect the integrity of our campuses and our public discourse, we must confront the reality that some digital activism is designed not to persuade, but to ostracize and radicalize. We must support the right to vigorous political debate while refusing to tolerate the coordinated degradation of Jewish identity. The hostage crisis has ended, but the digital war against Jewish life continues. Recognizing the tools of this mobilization is the first step toward stopping it.
