Excerpt:
Seventeen Pulitzer Prize-winning editorial cartoonists, including "Doonesbury" creator Garry Trudeau and 2010 winner Mark Fiore, have signed a petition to condemn "threats" against Matt Stone and Trey Parker, the creators of the Comedy Central show "South Park," by a group calling itself Revolution Muslim.
The group produced the site RevolutionMuslim.com -- on which images of the fatally stabbed filmmaker Theo van Gogh (a noted critic of Islam) appeared with the caption: "Have Matt Stone And Trey Parker Forgotten This?"
Comedy Central censored an episode of "South Park" last week that was to depict Muhammad. Depictions of the religious leader are considered blasphemous by some Muslims. Stone and Parker said Comedy Central also censored the show's speech about fear and intimidation.
