The New Vocabulary of Jew-Hatred

Twenty-two symbols, slogans, and items have surged into public spaces, social media feeds, and protest squares since October 7. Some are newly minted. Others are repurposed across centuries of antisemitism. All of them function as early warnings of incoming hostility toward Jewish communities. This is a guide to recognizing them.

A Symbol is Rarely Just a Symbol.

The October 7th massacre sparked an unprecedented global surge in antisemitism, manifesting across social media, public figures, media outlets, streets, international institutions, educational and cultural spaces, and houses of worship. Public discourse about the Hamas attack and the subsequent war in Gaza has been rife with antisemitic symbols and rhetoric — some newly invented, many borrowed from older hatreds and given fresh menace.

This atlas catalogues 22 of those signs. Not all of them carry strictly antisemitic meaning in every context. All of them, however, function as early warning indicators. Recognizing them — at a protest, on a wall, on a feed — is the first step toward responding to them.

Three forms. One message.

Visual Symbols

Visual symbols communicate without language. They appear as graffiti on Jewish institutions, as emoji buried in social-media replies, as patches stitched onto Hamas uniforms, as badges worn at protests. Because they require no translation, they cross borders and platforms in seconds — and because they often look harmless, they evade scrutiny while embedding deeply hostile meanings into everyday spaces.

02-slogans
Slogans & Chants

 Slogans are the verbal layer of the same campaign. Some are chanted in unison at rallies, some are spray-painted on synagogues, some are reposted as captions a hundred million times. They can sound like solidarity. They can borrow the cadence of human-rights language. But the substance — once decoded from the metaphor, the foreign language, or the Cold-War echo — repeatedly arrives at the same place: the denial of Jewish self-determination, and the justification of violence against Jews.

03-items
Items & Insignia

Items are the most tangible form. A scarf draped at a campus rally. A flag flown from an apartment window. A patch sewn onto a backpack. Some of these objects carry layered cultural meaning that long predates October 7; others are the official insignia of organizations dedicated to the destruction of Israel and the murder of Jews. In the post-October 7 context, both categories function as visible declarations of allegiance in shared public space.

INVERTED Red Triangle

The red triangle has increasingly appeared in anti-Israel propaganda as a symbol of hate and intimidation. Its manifestations range from social media emojis and graffiti on Jewish institutions to badges worn at protests, and most recently,  patches on Hamas Uniforms.

Facts & Historical Origins

Historically, the inverted red triangle was used to identify political prisoners during the Holocaust, symbolizing persecution and oppression. It later appeared on the 1917 Flag of the Arab Revolt and subsequently became part of the Palestinian flag. In recent years, Palestinian groups like Hamas have adopted it to mark targets during attacks, infusing the symbol with aggressive and violent connotations. Most recently, Hamas has incorporated the red triangle into patches worn on their uniforms.

Threat to Jewish Communities and Public Safety

The red triangle has been weaponized as a tool for hate, appearing in acts of vandalism such as marking Berlin Mayor Kai Wegner's residence and Tagesspiegel's headquarters, leading to its prohibition by the Berlin Senate in July 2024. In New York, the homes of Jewish leaders have been defaced with this symbol, signaling intimidation and potential violence. Its use perpetuates fear and hostility, making it a significant threat to public safety and Jewish communities worldwide.

The red triangle is weaponized to intimidate and incite hostility, repurposing a Holocaust-era symbol of persecution into a modern tool for hate against Jews.
