In September 2005, Thomas was one of several celebrities to speak at an anti-war rally in Washington, D.C. He also spoke out at the September 15, 2007 anti-war protest in Washington D.C. He blogs for "The Huffington Post". Thomas said he was inclined to be against the Iraq War, as he felt there was no clear reason to invade the country and the fact that some of his brother's friends who were deployed to Iraq, and upon learning about how terrified they were, decided to begin speaking out.
