"Americans who remember the student protests of the 1960s tend to assume that U.S. colleges are still some of the freest places on earth."

Says Greg Lukianoff:

But that idealized university no longer exists. It was wiped out in the 1990s by administrators, diversity hustlers and liability-management professionals, who were often abetted by professors committed to political agendas.

"What's disappointing and rightfully scorned," Mr. Lukianoff says, "is that in some cases the very professors who were benefiting from the free-speech movement turned around to advocate speech codes and speech zones in the 1980s and '90s."

Today, university bureaucrats suppress debate with anti-harassment policies that function as de facto speech codes....

At Western Michigan University, it is considered harassment to hold a "condescending sex-based attitude." That just about sums up the line "I think of all Harvard men as sissies" (from F. Scott Fitzgerald's 1920 novel "This Side of Paradise"), a quote that was banned at Yale when students put it on a T-shirt. 

More examples like that at the link — which goes to the Wall Street Journal — and in Lukianoff's book "Unlearning Liberty." There's video too at the link, displayed with this unintended freeze-frame humor:
