Here’s a great quote from free speech scholar Rodney Smolla:
The American experience with freedom of speech is important to the rest of the world not because our current First Amendment policies are necessarily wise — it is not that Americans have all the perplexing issues of free speech “right.” American thinking on freedom of speech is relevant to the rest of the world because our experience in wrestling with free speech conflicts and communications policy is unusually rich. American society may not have the best answers, but it has thought about the problems more. Under the American First Amendment, the United States has experimented more often than any other culture in the world with the radical presumption that it is better to err on the side of openness than repression, even when the public arguments for repression are alluring.
Found that gem from 1992 in a great journal article by my good friend Kyu Ho Youm.
