The American Council of Trustees and Alumni has issued a report that says outspoken professors who defy balanced course curricula and transmit their own political agendas to students are more common than might be believed. The report, called “How Many Ward Churchills?,” says that Mr. Churchill—the University of Colorado professor of ethnic studies who likened some victims of the World Trade Center attack to “little Eichmanns” and who just last week was found to have committed research misconduct (The Chronicle, May 17)—is not an anomaly.

Anne D. Neal, the council’s president, says a study of university and faculty Web sites turned up several examples of courses in which professors used their classrooms as “platforms for propaganda, sites of sensitivity training, and launching pads for political activisim.” The report says universities should not punish professors for what they say but should “expose them” and “invite them to debate ideas,” while ensuring that students have access to a wide range of “intellectual diversity” on their faculties.
