"McGruder doesn't shy away from controversy. After the Sept. 11, 2001, terrorist attacks, McGruder drew a series of strips featuring a talking American flag and a yellow ribbon -- and they had very critical things to say about the Patriot Act and the Bush administration. Some newspapers dropped those strips entirely."
