Progressives Against Free Speech?

I have no desire to take Glenn Beck's side, but there's something noteworthy here nonetheless. Last night on "Countdown with Keith Olbermann," Arianna Huffington of the Huffington Post suggested that Glenn Beck might properly be silenced by the State. She claimed that an exception to the free-speech doctrine is yelling "fire" in a crowded theater and that Beck every day commits the political equivalent of yelling "fire." A few minutes later she sort of backed off, saying that while he may not be legally liable if his viewers commit violence, he would be morally liable. Olbermann ate this stuff up.

Of course, Huffington got it wrong. The "fire in the crowded theater" matter is not an exception to free speech but a recognition of property rights, of which free speech is but a derivative. There's no right to "free speech" on someone else's property. If you buy a theater ticket and then endanger the audience by falsely yelling "fire," you have (among other things) violated the terms of your being in the theater. There's no need to claim an exception to the free-speech doctrine. Properly conceived, free speech is ultimately a property right.

What's with the progressives? Now that their guy is in power, are they ready to throw out civil liberties so flagrantly?
