Speech is absolutely free, so also is the right to not listen if you don't care to hear it.

Moreover, freedom of speech is the guaranteed right to say anything you want to say in a peaceful manner. Once you begin shouting, threatening, or carrying weapons you are no longer protected under free speech.

There is plenty of speech I disagree with. Just because I disagree does not remove the right of the speaker. What my disagreement does do is grant me as much of an equal right to speak (also peaceably) the opposing viewpoint (whether opinion or fact).

Free assembly is not as protected as free speech. Free assembly is only protected for a peaceful petition for a redress of grievances toward the government of the State. Assembly for the purpose of intimidating a person or group or threatening the safety of any member of the public is NOT protected.
