Or, Correcting Wrongthought. Bill Whittle on campus censorship and the narrowing of minds:  

65% of the 392 top colleges surveyed maintain speech codes and other restrictions on expression that violate First Amendment principles… No wonder a study of 24,000 students conducted by the Association of American Colleges and Universities in 2010 revealed that only 30.3% of college seniors strongly agreed with the statement that, “It is safe to hold unpopular opinions on campus”… The students were downright optimistic compared to the 9,000 campus professionals surveyed. Only 18.8% strongly agreed that it was safe to hold unpopular opinions on campus… As the sociologist Diana C. Mutz discovered in her 2006 book Hearing the Other Side, those with the highest levels of education had the lowest exposure to people with conflicting points of view, while those who have not graduated from high school can claim the most diverse discussion mates. In other words, the most educated among us are also the most likely to live in the tightest echo chambers.
