Name the mainstream (note mainstream) republican that threatened their life. Just one. Then you would win, otherwise this is just a strawman based on their PR campaign during their comeback. During that time there were undoubtedly some who did do that, but not even close to a percentage of those who simply "spoke" against their political grandstanding on the platform they helped them to gain with their support.
Again, please check my words. Which mainstream republican threatened their life? Pretending that both sides don't have their nuts that threaten lives is only pretense, but it is remarkable that you must resort to the absolute fringe to get the emotive power behind your words here. If I constantly sought the worst of those who carry a D to say that all "D's" were some way, it would likely be because I was partisan-blind.
During this period, according to a pretty good wiki article, at one concert they had metal detectors, at another there was a threat specific enough to have one member of the band escorted to and from the airport. I dislike the people who threatened them, I hope they were arrested and prosecuted.
The Wiki Article
Who said it? The constant drumming of "The Dixie Chicks" and "Rs are against the 1st Amendment" going together is who suggested it. They spoke against the war, while expecting to keep an audience largely made up of people who supported it.
And again, which mainstream republican even called for their arrest, let alone their death, for the use of their 1st Amendment right? Nobody in the mainstream suggested they didn't have the right to say it, they just said they would no longer give them the platform from which to speak. If the Dixie Chicks were going to continue to have the platform, it would be with money from a different source of fans.
You continuously get upset for others using the same right, and try to shut down conversation with the emotive "they threatened their lives!" The overwhelming majority of those people never threatened anybody in their lives, let alone the Dixie Chicks with anything more than simply the loss of their support.
Dragging the conversation down to the lowest of denominators because you do not have the ability to bring this back up to a logical discussion doesn't make you right, just more emotive. Where and how you spend your money can be as much of a 1st Amendment expression and for some is the only one that they have that has any power when those people they support with money start their forays into the political realm.
The Dixie Chicks spoke their mind, so did their audience.
I don't seek to defend the people who sent them threats, that's simply illegal, I seek to defend the millions that simply stopped paying and spoke with their wallets. Those people merely expressed a different side of that same Amendment.
And as for "illegal war", many would agree, others would disagree. If you were a performer that had an audience made up of those that disagree with that statement it would be foolish to expect to keep that audience if you expressed that opinion in such a manner.
Were my audience largely made up of people who voted for Bush, I would not expect there to be no negative reaction to my expression once I ventured into the political arena if I consistently spoke against him.
They have as much right to simply stop supporting people with money who will use that money and fame to create a platform for ideas that are not remotely compatible with their own.
