A few years ago, Airborne settled a lawsuit based on their claim that their product would help prevent colds. That can be considered a measureable statement of fact. Based on their ad, if you take Airborne, you shouldn't come down with a cold. There is not any evidence that proves that. This is deceptive advertising because they stated what could be considered a proven fact, yet it wasn't fact and hadn't been proven.
I don't think that legislation to verify voter identification falls under the domain of unintentional or intentional discrimination. I think it's great that we are verifying the identity of each and every voting person. We are not denying a voter their rights based on sex, race or religion. We are verifying that they have the right to vote. I think this is a very touchy subject. However, I am also inclined to believe that if a person doesn't pay taxes, they shouldn't be afforded the right to vote on how we spend the money. There is no way to verify these things without verifying the identity of voters.
