Freedom of speech is governed by legal restrictions and public mores. And what most of us have discovered is that a multicultural society means more 'mores' and more people to offend. That has taken us from one general set of social speech codes that governed such things as obscenity and public abuse, to a thousand fiefdoms of speech in which every group strives to impose its own speech codes in public forums. The Constitution still protects some forms of political speech for now, but it is a weak and fitful defense in a society where it is not the content of speech that matters, but who is offended by it.
