After Comedy Central censored depiction of Muhammad in a South Park episode, after death-threat from a Muslim group, RevolutionMuslim.org, Seattle cartoonist Molly Norris launched "Everybody Draw Muhammad Day" to defend one's right to free expression and to challenge the boundaries of political correctness.

I make cartoons about current, cultural events. I made a cartoon of a fictional ’poster’ entitled “Everybody Draw Mohammed Day!” with a nonexistent group’s name — Citizens Against Citizens Against Humor — drawn on the cartoon. It was in specific response to the recent censoring of a South Park episode, a desire to bring home the importance of the first amendment. I did not intend for my cartoon to go viral. I did not intend to be the focus of any ’group’. This particular cartoon has struck a gigantic nerve, something I was totally unprepared for.
Now the Morris too backtracked from offending Muslims, Stop Islamization of America (SIOA) has taken over the project to carry it over. You are invited to draw cartoons on Muhammad and upload them in their Facebook group.
