If some moron wants to sing the praises of Ted Kennedy over his cell phone, as long as it doesn't disrupt my peaceful corner, he's free to do so. But if the same moron starts saying, in the same volume, that he wishes we would lose the war in Iraq or that NAMBLA is a great organization, then that's when I get out of my chair. I will decide on my course of action en route to his location. Afterward I will take whatever punishment the court deems necessary, but I will not sit idly by while the punks take over.
So you prefer the concept of free speech to only apply when you agree with the subject? Or, at least don't militantly disagree?
