StopAntisemitism – Bias and Credibility

---

QUESTIONABLE SOURCE

A questionable source exhibits one or more of the following: extreme bias, consistent promotion of propaganda/conspiracies, poor or no sourcing to credible information, a complete lack of transparency, and/or is fake news. Fake News is the deliberate attempt to publish hoaxes and/or disinformation for profit or influence (Learn More). Sources listed in the Questionable Category may be untrustworthy and should be fact-checked on a per-article basis. See all Questionable sources.

• Overall, we rate StopAntisemitism as Right Biased based on its strong pro-Israel advocacy, alignment with conservative donor networks, and consistent framing of Palestinian solidarity as antisemitic. We also rate it Questionable and mixed for factual reporting due to its documented false claims, doxxing tactics, selective sourcing, and conflation of legitimate criticism with hate speech. While it effectively identifies genuine extremist threats, its pattern of ideological targeting and misinformation significantly lowers its reliability.

History

StopAntisemitism is a U.S.-based watchdog organization founded in 2018 to document and expose antisemitic incidents and individuals. The group was established in response to rising antisemitic sentiment and violence and claims to reach millions through social media and its website. The organization is led by Executive Director Liora Rez, who has been listed multiple times on The Algemeiner’s “Top 100 People Positively Influencing Jewish Life.”

StopAntisemitism operates by gathering user-submitted tips of alleged antisemitic incidents and vetting them before public exposure. The group’s model centers on a “name-and-shame” approach, which Rez argues creates accountability but which critics have described as public doxxing. It also publishes weekly and yearly “Antisemite of the Week/Year” designations, which have included a mix of verified hate figures and individuals critical of Israeli government policies.

Funded by / Ownership

StopAntisemitism is funded by the Milstein Family Foundation and the Merona Leadership Foundation, both of which are associated with pro-Israel philanthropists Adam and Gila Milstein. The Merona Foundation pays the Executive Director’s salary and contributes roughly $270,000 annually for operational expenses. The group’s stated purpose is nonpartisan, but its funding and messaging align with the broader U.S. pro-Israel advocacy ecosystem.

Analysis / Bias

StopAntisemitism’s mission, to combat antisemitism, is legitimate and crucial. Its pages on extremist groups, such as Patriot Front, the Nation of Islam, and the Goyim Defense League, accurately describe known hate organizations and demonstrate transparent reporting on violent antisemitism. Its IHRA definition page aligns with the internationally recognized standards of the International Holocaust Remembrance Alliance.

However, the organization frequently blurs the line between antisemitism and political criticism of Israel. Its “Antisemite of the Week” series often labels public figures—including actors, journalists, and activists such as Cynthia Nixon, Cenk Uygur, Ana Kasparian, and Ms. Rachel—as antisemites for expressing opposition to Israeli government policy or referring to events in Gaza as genocide. Critics, including Defector and Calcalist, have accused StopAntisemitism of targeting progressive or pro-Palestinian voices under the guise of combating hate.

The group has also promoted misinformation, such as false claims in 2023 that images of Palestinian babies killed in Gaza were “dolls,” which were later debunked. These repeated missteps, coupled with selective framing and public shaming tactics, have led media analysts to view the organization as advocacy-driven and unreliable for neutral reporting. While the site’s College Antisemitism Report provides data and insights on campus hostility toward Jewish students, its framing often links organizations like Students for Justice in Palestine to antisemitic activity without evidence of direct incitement, reinforcing a narrative aligned with right-leaning pro-Israel activism.

In sum, StopAntisemitism provides legitimate information on hate groups and real antisemitic incidents but undermines its credibility through partisan targeting, selective interpretation of antisemitism, and documented factual errors.
