On May 29, 2015, Abraham Foxman, then the national director of the Anti-Defamation League, authored an op-ed published by the JTA, entitled, "Comprehensive approach to fighting BDS is needed." With respect to the question of legislation seeking to quash BDS and other activism critical of Israel - both at the state and federal levels - Foxman notes (among other things):
Legislation that bars BDS activity by private groups, whether corporations or universities, strikes at the heart of First Amendment-protected free speech, will be challenged in the courts and is likely to be struck down. A decision by a private body to boycott Israel, as despicable as it may be, is protected by our Constitution. Perhaps in Europe, where hate speech laws exist and are acceptable within their own legal frameworks, such bills could be sustained. But not here in America.
Full text of that op-ed is included below, or can be viewed on the JTA website.
