Meta’s Oversight Board recently opened a case to explore the issue of Holocaust denial on its platform and invited public comment. With discourse from the Hamas-Israel war raging across social media platforms – and Holocaust denial being levied at supporters of Israel along with false claims that Israel is waging a genocide against Palestinians now – the issue has only gained added urgency. The Brandeis Center (LDB) sent a letter to Meta’s Oversight Board highlighting Meta’s policy banning hate speech from the platform – while failing to remove postings of Holocaust denial. The Brandeis Center’s letter recommends that the Oversight Board encourage Meta to treat Holocaust denial as “Tier One hate speech” and to help fight against Jew-hatred by “improving its algorithms, better training content moderators, and working with Jewish users and groups to understand how they experience anti-Semitism online and stand up against it.” LDB’s letter clearly defines Holocaust denial using the International Holocaust Remembrance Alliance (IHRA) working definition of Holocaust denial and distortion, which includes denying the historical facts of the genocide carried out against the Jewish people by Nazi Germany. Distortion of the events of the Holocaust or blaming Jews for their own extermination also falls under the category of Holocaust denial. IHRA, the United Nations, and the Organization for Security and Co-operation in Europe all have declared that Holocaust denial is a form of anti-Semitism. When faced with a free speech argument, the European Court of Human Rights stated that “[d]enying crimes against humanity is therefore one of the most serious forms of racial defamation of Jews and of incitement to hatred of them.” LDB also reminded the Meta Oversight Board that the United Nations and U.S. have called on social media companies to aid in combating the spread of anti-Semitism, including Holocaust denial. Additionally, after seeing an increase in anti-Semitism, the U.S. National Strategy to Combat Antisemitism states that social media companies have a responsibility to fight against hate. LDB’s letter to the Oversight Board explains that Meta can abide by the National Strategy’s request by “improving its algorithms, training community moderators, ensuring access to credible information, and working with and listening to Jewish users and groups.” These recommendations, along with the adoption of the IHRA definition of Holocaust denial, would bring Meta in line with international standards. Anti-Semitic hate speech must be treated the same as all other hate speech on Meta’s platform.
