“A well-functioning democracy has a culture of free speech, not simply legal protection of free speech. It encourages independence of mind. It imparts a willingness to challenge prevailing opinion through both words and deeds. Equally important, it encourages a certain set of attitudes in listeners, one that gives a respectful hearing to those who do not embrace the conventional wisdom. In a culture of free speech, the attitude of listeners is no less important than that of speakers.”
