What is the current state of the law on freedom of speech?

Any departure from absolute regimentation may cause trouble. Any variation from the majority's opinion may inspire fear. Any word spoken, in class, in the lunchroom, or on the campus, that deviates from the views of another person may start an argument or cause a disturbance. But our Constitution says we must take this risk, Terminiello v. Chicago, 337 U.S. 1 [69 S.Ct. 894, 93 L.Ed. 1131] (1949); and our history says that it is this sort of hazardous freedom--this kind of openness--that is the basis of our national strength and of the independence and vigor of Americans who grow up and live in this relatively permissive, often disputatious, society.
