Students are back on college campuses in North Carolina and across the country, and you might expect them to be filling their minds with a range of viewpoints on the most contentious political and philosophical issues.

But Robert Shibley, executive director of the Foundation for Individual Rights in Education, warns that too many students face restrictions on free speech. Sometimes these restrictions take the form of formal campus speech codes. In other instances, administrators, faculty members, and even students themselves are taking steps to limit speech by other means.

Shibley discusses threats to free speech on campus during an interview for Carolina Journal Radio.
