Jim Emerson has a good take on the Free Speech issues involved in the Rush Limbaugh matter.
Here's my renewed way of looking at the issue: If you believe in Free Speech, you have to occasionally defend that principle with regard to those who say things you find noxious or offensive. They don't have the right to be paid for saying it. They don't have the right to have a TV or radio show on which to say it. They don't have the right to say it and go unrebutted. They don't even have the right to say it and suffer no consequences like sponsor or audience desertion. But they do have the right to say it and we should all do more to protect that right. I'm going to try to do more on my part.
