Perhaps I missed something, I don't see anyone saying that they didn't have the RIGHT to speak their minds or voice their opinions, or that they can't pose nude. I agree, the death threats are ridiculous, but if their fan base decides not to buy their records or go to their shows because they disagree that is THEIR right and freedom.
Regardless of what their views are, being public figures such as they are they need to take that into consideration before opening their mouths. They alienated their fan base with those comments, like it or not. Most Country Music fans are also fanatical patriots who will stand by their country and President right or wrong. Did Natalie have the RIGHT to say what she did? - definitely. Will it destroy their career? - probably. This isn't a one side is right, the other is wrong issue. Both sides are using their own freedom of expression. None of the Dixie Chicks are going to jail because of what they said.
