Notice the outer ring--the toleration zone--deals with issues arising when, say, a private employer fires you for speech that offends someone. The employer's decision to fire you is not within the First Amendment, because the First Amendment only prohibits government from abridging the freedom of speech. Nevertheless, in a society that values free speech and tolerance, employers should not punish employees for their off-the-job speech. And it is intolerant for one to demand that speakers be fired. If you value tolerance, then be tolerant for everyone, not merely those who say things you like.
