Polarizing political beliefs are nothing new on campus, but the tactics employed by supporters of the Boycott, Divestment, Sanctions (BDS) movement create new cause for concern, from the politicization of curricula and academic associations to efforts to silence Israeli speakers to overtly anti-Semitic behavior on campus. In a new essay, the American Council of Trustees and Alumni renews its call for the protection of campus free speech and free expression by warning trustees and higher education leaders about the threat to academic freedom from the BDS movement. The report outlines ways to safeguard academic freedom and institutional neutrality and create a campus climate where a wide range of social and political thought is represented in important debates.
