Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
In my opinion, this group received unfair treatment from the American people in general and the media in particular. Their opinions of the war and the President should have been accepted for what they were at the time - free speech. That being said, the Dixie Chicks are fantastic. I love their music and DVDs. Step above the rhetoric and hate from the right and listen to their music. It is simply fantastic.
