The basic premise has little to do with the Dixie Chicks. They're just a footnote.
It just happens too often that when someone, usually espousing liberal views, mouths off and catches heat for it, they usually go running to the skirts of the First Amendment saying that their rights are being violated when someone says something equally nasty BACK. No one ever said freedom of speech meant people have to like what you say or shut the hell up. It only means if you criticize the *government* they can't shut you up. The latest dust-ups coming from Franken and Moore and now Clooney are, it's art, it's comedy, it's satire, we can insult you endlessly without even being fair or factual BUT when you take a shot back it's infringing on my rights. Well that is wrong, it's even logically wrong - what's good for one side is good for both.
BUT - and this is the part I was referring to - the same people who say this are wholly on the side of political correctness. These are usually the same kinds of people who say the name Redskins is offensive and must be changed. That there are certain things and words that cannot be tolerated. This is of course, hypocritical.
If insulting the President is totally fair game, so should any other speech that someone finds offensive.
Sorry to bring it up *here* - but I'm continually annoyed by the double-think that says that my offensive speech needs to be protected but your offensive speech must not be allowed. ("You" in the generic sense, of course).
