It's worthwhile to remember free speech is not absolute. There are several cases where it's not considered free speech, here are some examples:
Obscenity
Fighting words
Defamation (includes libel, slander)
Child pornography
Perjury
Blackmail
Incitement to imminent lawless action
True threats
Solicitations to commit crimes
I know people love to protect freedom of speech and I'm on that bandwagon, but please let's remember just because it appears freedom of speech is being violated doesn't mean it is (e.g. in cases were most people don't support something and it appears the mob rule is triumph, it should indeed be sign that something may be wrong but let's not use that sign as enough evidence that free speech is violated.) Sometimes it's not the freedom of speech that is being violated, but some person's rights.
