Free speech guru Steve Simpson at the Ayn Rand Institute has an excellent piece on Why our campuses are boiling over in left-wing rage instead of discourse | The Hill:

To fight these ideas and the culture they’ve spawned on campus will require more than complaining about college “snowflakes” or political correctness. We need to defend the ideas on which free speech depends, most notably reason and individual rights.

The purpose of the right to free speech is to protect our right to think for ourselves and to communicate with others, which are two of the pillars of a modern, free society. True, people can and often do say absurd and horrible things. But it’s false to equate even hateful speech with use of force.

Force is qualitatively different from speech. No matter how harsh speech is, you are always free to ignore it and walk away. Not so with force. If you doubt this, ask Ayaan Hirsi Ali, Flemming Rose, or the many other individuals currently on jihadist hit lists whether they would prefer to live under the threat of death or the threat of hateful speech.

That’s not to say that speech can never be used in the commission of a crime. It is entirely proper to criminalize actual threats, incitement to violence, and the like. But that’s because what is being threatened is the use of force. If those who use offensive or hateful speech cross the line into actual threats or incitement, then it is proper to prosecute them. But short of that, they must be free to speak.

Ayn Rand once said that “a gun is not an argument.” The reverse is also true: an argument is not a gun. If we forget the difference, we will end up with guns settling our disputes, rather than arguments.

Simpson’s article is excellent and the entire piece is worth a read as well as the collection of essays he has put together in his book Defending Free Speech.
