Way back in the 60's Larry Norman could speak and play freely on campus.  Hal Lindsey
 was allowed to debate Christianity openly on campus...

 Much of the 1960s counterculture originated on college campuses. The 1964 Free Speech Movement at the University of California, Berkeley, which had its roots in the Civil Rights Movement of the American South, was one early example. At Berkeley a group of students began to identify themselves as having interests as a class that were at odds with the interests and practices of the University and its corporate sponsors. Other rebellious young people, who were not students, also contributed to the Free Speech Movement.

Today they would not be allowed to speak.
 
"The WSJ catches up with FIRE's Greg Lukianoff and his crusade to expose how universities have become the most authoritarian institutions in America. In Unlearning Liberty, Lukianoff notes that baby-boom 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. But that idealized university no longer exists. Today, university bureaucrats suppress debate with anti-harassment policies that function as de facto speech codes. FIRE maintains a database of such policies on its website. What they share, lifelong Democrat Lukianoff says, is a view of 'harassment' so broad and so removed from its legal definition that 'literally every student on campus is already guilty.'"
