Not only did they scale the wall in Cairo, in a separate incident in Benghazi, Muslim protestors killed the U.S. Ambassador to Libya, and three other people.
I know we focus on Christianity a lot on this board, because many of us are in America and are used to Christian hegemony in American culture and politics. But I don't believe there is any room in a civilized world for a religion that is so insecure that it must kill people who have the temerity and unmitigated gall to criticize its imaginary god and magical prophet.
Muslims, you're a part of the human race. You're not immune from human criticism. It doesn't matter how "right" you think you are--you don't have the right to kill in the name of protecting your religion from films, books, or art that says something you don't agree with.
Get with the 21st century.
