In our December 2023 report, we documented the level of anti-Jewish and anti-Israel hostility on 51 US campuses since the October 7 Hamas attack on Israel. One question prompted by our findings was how Jewish students “draw the line” between acceptable political discourse and antisemitism. Guidelines developed to define antisemitism (IHRA, NEXUS, JDA) agree that while criticism of Israel is not necessarily antisemitic, particular statements can be, depending on the broader context. This report explores which forms of anti-Israel sentiments are viewed by Jewish college students as “crossing the line” into antisemitism, including critical statements about Israel that have received attention during the ongoing Israel-Hamas war. The findings are based on survey data collected in November-December 2023 from more than 2,000 Jewish undergraduate students at 51 US colleges and universities with large Jewish student populations. <br>
