Hardly a week goes by without another controversy over free speech on college campuses. On one side, there are increased demands to censor hateful, disrespectful, and bullying expression and to ensure an inclusive and nondiscriminatory learning environment. On the other side are traditional free speech advocates who charge that recent demands for censorship coddle students and threaten free inquiry. Chancellor Gillman discusses why campuses must provide supportive learning environments for an increasingly diverse student body but can never restrict the expression of ideas. After discussing the central arguments for prohibiting the censorship of ideas on campus, Gillman reviews what colleges can and can’t do when dealing with free speech controversies, including controversies around large-scale demonstrations that create risks of violence.
