One odd thing about Islam, is that the "bad stuff" we know about their historical origins -- the ugly details about Muhammad, for instance --- aren't things we learn from their critics, their rivals, or their victims. It's from the "Sacred Writ" of Islam itself, the Hadith, the Sunna, and the Koran --- that we know that Muhammad was deranged (either deranged, demon-driven, or a thorough charlatan), and a bloody-handed serial-rapist-pedophile.
It's in their Scriptures! They think he's perfect!
