The big problem with islam is that Muhammed has left behind his holy work with his greasy, blood stained fingersprints all over it.
The Koran which contains overwheliming evidence that this poor excuse for a prophet is actually a whacked-out child predator who demands his people kill humans that are other than muslim.
Any shyster that promises 72 virgins to those who deliberately die while killing thousands of innocents has to be suspected as a person whose IQ and demeanor is below that of Charles Manson.
