Supporters of the NSA wire-tapping and of the PATRIOT Act assert that if we have nothing to hide, why should we be concerned. Consider that an administration may construe any criticism of itself to be criminal and covered by the PATRIOT Act. Don't laugh, but there have been people who have privately called their leaders jerks and put in prison for it. Don't laugh, Joseph McCarthy hounded people for their political beliefs. Don't laugh, Richard Nixon had his enemies list of people who were critical of his policies. Don't laugh, George W. Bush said, "You are either with us or against us."
But how many of these same people don't apply the same reasoning to corporate labels. If a corporation has nothing to hide in its products, then why is it concerned about laws concerning labeling? If GMO foods are good for you, then what do corporations have to hide in having laws past to prohibit labeling foods as GMO?
If various political front organizations of any stripe have nothing to hide, why do they need 501(c) status? Could it be that the law requires candidates to give the names of their donors but a 501(c) organization doesn't have to? If you live in California and want to contribute to a candidate in Wisconsin, why do want to hide that you are an out-of-state donor?
Consistency has never been a hall-mark of those with uncompromising political mind-sets.
