There is no question Natalies mouth cost the sisters millions of dollars.
However, they are so wealthy and they will always have their live shows, they'll be fine.
"Millions"?

Again you demonstrate a profound ignorance of the music industry.
I'll tell you what it
didn't cost though --- their integrity. Though there's no way to put a number on that, they could have sold out and capitulated.
But -- they didn't.
And that right there is the happy ending.
They didn't have to "sell out" as you put it, they simply could have done what most all other performers have always done, and separated her politics from her performance.
Simple really.
Like Ted Nugent?
Like Toby Keith?
There ain't nothing "political" about standing up for your state amid the obvious association, that being both the band and the President representing Texas. That's number one.
And number two is the elephant in the room. Exactly what part of the largest protest event in the history of the world, which is the environment they were sitting in at the time ----- don't you get?
And I would expect that Keith and Nugent are not exactly big sellers in the community of liberals, just as the Chicks are not big in conservative circles now.
Ummmm.... didn't you just say keep the politics out? Now you want 'em back in again? Having it both ways: Priceless.
Doesn't work as analogy anyway. The analogy would be, did the establishment music/media industry then conspire to deprive Ted Nugent or Toby Keith of record sales? Show me that, and I'll be all over them defending the artists. Even poopy-pants.
And for the Chicks and their location at the time, yeah, I'm certain their hosts for the most part loved their comments, but again it didn't go over so well for them here.
And
AGAIN, they said it there, to them, not here to us. Are we still unclear on the concepts of "here" and "there"?

Don't make me whip out another map on your ass.
The question I keep asking, and you keep valiantly running away from, is what the **** business is it of ours to go scraping around the world to find things that if expressed here we would pretend to find "offensive"? How PC-fucked up IS that?
That's your cue, run away again.
This was not an issue of integrity, we don't require our performers to publicly take sides, and either denounce or applaud our leaders. No one was expecting the Chicks to publicly say anything other than to discuss their music.
Considering that
three million Londoners had just protested in the streets about a war being mongered by a guy who ostentatiously associates specifically with Texas, and considering that same audience is watching a band comprised of three people who also ostentatiously associate specifically with Texas ---- yeah I'd say it was very much expected. That's exactly why I'm calling it "the elephant in the room". That's a phrase referring to an undercurrent that cannot be ignored. So Maines addressed it in an act of reassurance.
And you want to tell us she can't do that, huh?
In fact you could say that by representing Texas as a bunch of warmongers, Dubya was already infringing on the Chicks' business opportunities. They could sue.
I shoulda been an attorney.
