Moore's sign reads "WE ARE ALL MUSLIM." Whaaaaat? You mean we all commit mass murder of infidels? Support Sharia law as a replacement for the Constitution? Set off bombs at the Boston Marathon? Shoot 30 or so soldiers at Fort Hood? Fly planes into skyscrapers? Behead non-believers? Kill our daughters for acting too western? Clitoraly mutilate young girls? Beat our wives? Drink camel pee?
It is no surprise that a far-out leftist like Michael Moore would openly demonstrate in favor of evil. The more odious an ideology is, the more leftists love it.
