There was a time (think back 8 years before the Bush-Cheney regime) when Americans were free to speak out in many ways, including comments on t-shirts. The Bush-Cheney regime have successfully quashed many of these rights.
In the latest onslaught against our civil liberties, citizens wearing t-shirts displaying the Constitution's Article 11 section 3 were denied entry to view the U.S. Constitution at the National archives. It was viewed as "political" even though folks with Hillary Clinton t-shirts were granted entry to the National Archives.
This is the Bush-Cheney Fascist version of democracy....regularly, American citizens are being told how to dress and what to wear or they are barred entry to government buildings and even transportation on airplanes.
