The Alliance for Academic Freedom is an organization of liberal and progressive academics that combats infringements on academic freedom relating to the Israeli-Palestinian conflict on college campuses, including academic boycotts of Israel.
In a statement they said: “We oppose the Anti-Semitism Awareness Act now before the US Congress because we believe it endangers academic freedom, too. We believe its language could encourage punishments of legitimate expressions of political opinion. We don’t believe that Congress should be in the business of setting forth official definitions of ant-Semitism. And we do not think any definition of anti-Semitism, including one originally drafted with the needs of European data collectors utmost in mind and then adopted (with minor changes) by the US Department of State for diplomatic purposes, has any legitimate application by Congress to contentious political speech on campus”.
