(THE AMERICAN INTEREST) — During the 1990s, the most high-profile means of ideological enforcement on campus were “speech codes,” or overly-broad harassment policies that could get students and faculty in trouble for controversial remarks related to race and gender. In recent years, according to the Foundation for Individual Rights in Education, the number of speech codes has declined, but new means of silencing provocative speech have emerged. Among them: “Disinvitation attempts,” or protests pressuring campus administrations to bar unpopular political figures from coming to campus after they had been invited to speak to a graduating class or student group (or drive them from campus once they have arrived).
Heterodox Academy, a non-partisan group of faculty dedicated to preserving viewpoint diversity in academia, has produced data about the frequency of such instances over the last 16 years. Their key findings: Efforts to bar speakers from campus appear to be on the upswing, and, since the beginning of the Obama years, it has been the campus Left that has been doing most of the disinviting.
