Without free speech no search for truth is possible... no discovery of truth is useful.
Better a thousandfold abuse of free speech than denial of free speech.
Free speech is meant to protect unpopular speech. Popular speech, by definition, needs no protection.
By placing discretion in the hands of an official to grant or deny a license, such a statute creates a threat of censorship that by its very existence chills free speech.
The Framers of the Constitution knew that free speech is the friend of change and revolution. But they also knew that it is always the deadliest enemy of tyranny.
Criticism of government finds sanctuary in several portions of the 1st Amendment. It is part of the right of free speech. It embraces freedom of the press.
That said, the question remains: how to strike the balance between free speech and mutual respect in this mixed-up world, both blessed and cursed with instant communication? We should not fight fire with fire, threats with threats.
