Antisemitism can no longer be considered a relic of the past or an extreme manifestation of marginal ideologies. In the modern world, it has evolved into a rapid and adaptive form of hatred, capable of moving seamlessly from the online space into real life.

Antisemitism has long moved beyond narrow radical communities and turned into a systemic phenomenon actively developing in the digital environment. Its danger lies in its rapid dynamics. Ideological narratives related to antisemitism spread instantaneously across social media, take root in people’s consciousness, and over time find expression in acts of violence.

A key feature of modern antisemitism is its hidden nature and integration into the public sphere. It rarely manifests in an overtly aggressive form. Instead, it masks itself as “analytics,” a “search for truth,” or “public debate.” Antisemitism can exist even in environments that consider themselves neutral, often manifesting not openly, but through hints to avoid criticism.

Australia faced the consequences of this transformation directly.

The Australian Case and the Rupture of Imaginary Security

A violent incident in Sydney in December became a moment of sharp awakening for Australian society. A country that had long perceived ideological terrorism as a problem concerning only other regions was forced to reconsider its own perceptions. Commentaries in Le Monde noted that Australia’s geographical distance created a false sense of security – specifically, the belief that radical processes already reaching Europe and the United States would have no consequences for the country.

This conviction proved to be false.

A particular resonance was caused by the realization that the attack was not unexpected. Warning signals had existed for years. Experts spoke of systemic online radicalization and an environment saturated with conspiracy theories, dehumanization, and ideological rhetoric. As in many previous cases in Western countries, the violence did not arise suddenly. It was carefully prepared through texts, images, and repetitive messages long before the physical attack.

For Jewish communities in different parts of the world, this scenario has long been far from new.

A Sequence of Events Culminating in Tragedies

Modern antisemitism rarely appears out of thin air. It forms a consistent chain from verbal or online harassment to overt violence. This process leaves behind a documented trail.

In January 2015, four people were killed in the Hyper Cacher kosher supermarket in Paris. They died during an ordinary trip for groceries solely because of their Jewish identity. After the tragedy, the families of the victims spoke of a breakdown in everyday life: the moment when habitual actions ceased to be safe, and domestic life was no longer neutral. What had existed for years in the form of verbal harassment moved into a deadly phase.

That same year, Paris experienced another massive terrorist attack at the Bataclan concert hall. Although the victims were of various backgrounds, Jewish sites and the Jewish community had already been identified in extremist narratives as permissible targets for violence. French intelligence services later confirmed: antisemitic ideology was not a side element but formed the foundation of the attackers’ worldview. It was built over years through hate speech, normalized harassment, and repetitive depictions of Jews as enemies of the social order.

In October 2018, eleven people were killed at the Tree of Life synagogue in Pittsburgh. This was the deadliest antisemitic attack in U.S. history. An analysis of the shooter’s online activity showed his deep involvement in conspiracy theories where Jews were represented as corruptors, manipulators, and the culprits of social problems. Survivors later emphasized that the path to tragedy did not begin with a physical attack, but with prolonged informational pressure, hate speech, and digital harassment that society had become accustomed to ignoring.

In October 2019, an attacker attempted to storm a synagogue in Halle, Germany, on Yom Kippur. Failing to enter, he killed two people nearby. The investigation established that the motives for the crime were formed in the online environment on forums, in streams, and in comments where antisemitism was cultivated as a form of identity and harassment became part of self-expression.

Violence does not begin with gunshots; this thought unites witnesses of tragic events worldwide. Violence begins with language, with permission, with the normalization of hatred, and from the moment when systemic harassment is no longer perceived as a threat.

Hidden Narratives in Modern Antisemitism: The Case of Uri Poliavich

Antisemitism in the 21st century rarely looks like open aggression. Most often, it masks itself as “questions” and “assumptions.” Phrases like “it’s worth a closer look,” “see how it all fits together,” or “too many coincidences” push the audience toward their own conclusions. Jewish origin is not named directly in such narratives but is silently presented as the explanation.

It is according to this principle that an online campaign has been built for years around Uri Poliavich, a Jewish entrepreneur whose name constantly appears in social networks, blogs, and collectively edited reference resources. These are accusations and hints of financial wrongdoings, despite the absence of any court rulings regarding Uri Poliavich, the absence of sanctions from regulators, and the endless circulation of the same assertions.

The materials are often presented as investigative journalism. In reality, they are based not on facts, but on fabrications and insinuations.

In December, a post on the X platform contained a direct accusation against a company associated with Uri Poliavich. It was an accusation of a serious criminal offense specifically, “money laundering” without any reference to a court decision, official investigation, or actions by oversight bodies. The tone of the publication was categorical and offensive. In a legal sense, it was libel.

Subsequent comments removed any doubts about the subtext. In the same discussion thread, remarks appeared in Greek, likely directed specifically at Uri Poliavich. In them, Jewish identity was presented as an obvious explanation for the alleged criminal activity:

“Even if you don’t know his name, it’s obvious he’s a Jew.”

Such statements are neither criticism nor analysis. This is the direct use of ethnic and religious affiliation as a stigma intended to “bolster” accusations. They reproduce one of the oldest antisemitic tropes in Europe: the identification of Jews with hidden finance, corruption, and conspiracies.

This is modern antisemitism: adaptive, mass-produced, and built into platform logic.

Harassment as a System

The peculiarity of the situation surrounding Uri Poliavich lies not in one specific post, but in their accumulation. Messages migrate from social networks to blogs, from blogs to edits of encyclopedic articles, and from there back to social networks. With each cycle, the context disappears, and every repetition creates a sense of a “well-known fact.” In this way, suspicion gradually transforms into a supposedly established reputation.

Consequently, reputational damage becomes systemic.

For individuals like Uri Poliavich, the consequences are practical. Business networking becomes strained, security requirements increase, and public exposure creates additional vulnerabilities. The very fact of success begins to arouse distrust. An indirect but consistent message that the right to legitimacy is conditional sounds constantly.

Experts researching antisemitism have long emphasized that such an environment causes damage not only psychologically. It forms a social atmosphere in which Jews are perceived as targets. First metaphorically, then in physical reality.

Platforms Without Restraint Mechanisms

Social platforms insist on their own neutrality. In fact, they act as accelerators. Algorithms encourage emotionally charged content, moderation is delayed, and management structures are detached from the consequences.

Today, antisemitism does not spread through private conversations. It grows because slanderous hints, hate speech, and coordinated harassment remain online, are cited, and reproduced. Comments, timelines, and encyclopedic pages turn into repositories of suspicion.

Security experts have warned for years that the normalization of such digital narratives often precedes offline violence. The people who carried out attacks in various countries were shaped by an environment where antisemitic claims did not receive a systemic rebuff.

The shock described by the media in Australia lay not only in the acts of violence themselves but also in the failure to recognize the danger signals in time. Geographical distance did not provide protection, nor did the denial of the problem.

Closing the Distance Between the Screen and Reality

Harassment directed at individuals, including Uri Poliavich, may seem distant from mass violence. In reality, these are different points on the same spectrum.

Reputational undermining, ethnic labeling, and conspiracy theories form a space in which Jews begin to be considered legitimate targets of violence, first at the level of words, then at the level of actions. Every publication left without a reaction lowers the barrier for the next one. Every hint expands the boundaries of permissible hatred.

As long as social platforms remain without moral, legal, or structural accountability, antisemitism will continue to gain momentum. And along with it, the distance between an online post and its consequences in the real world will continue to shrink.

History has repeatedly shown where this leads. Today’s difference lies only in the speed of distribution.
