I cannot say much more than Eugene Volokh does on this subject, but when you read this story about the University of Hawaii, Hilo campus, please notice that the university administrators say that there is a special “free speech zone” where student organizations may hand out pamphlets.
It is between the theater and the new student services building, like a tolerated smoking zone where obnoxious social habits may be freely practiced, before they are finally expunged from the University.
A friend who had lived in Honolulu for three years said that the political culture of Hawaii was a blend of Huey Long Democrat and Imperial Japan. I guess the University there reflects the general conformist and obedient brainlessness. Trouble is, has the brainlessness spread to Hilo from Harvard?
