In response to the rising challenge of online antisemitism, American Jewish Committee (AJC), B’nai B’rith International, the Institute for Strategic Dialogue, UNESCO, and the World Jewish Congress came together to host an action-oriented online capacity building workshop. The session united over 50 transatlantic civil society leaders, online antisemitism experts, and leading figures driving policy responses to hateful narratives as well as fostering media and information literacy, to share best practices around countering online antisemitism from across Europe and North America.
