What’s wrong with the Anti-Semitism Awareness Act?

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.
