Robert Spencer is another member of this bloody cabal. He is one of the most active Crusaders and he has authored a few best-selling propaganda books to justify genocide against Muslims, such as: The Complete Infidel’s Guide to the Koran, The Truth About Muhammad: Founder of the World’s Most Intolerant Religion, The Politically Incorrect Guide to Islam (And the Crusades), and Religion of Peace?: Why Christianity Is and Islam Isn’t.
