It is a trick answer Roy, which religion DOESN'T say there will be some punishment after death if you don't drink the Kool Aid? 

And do you really have to go back a thousand years to the Crusades? Are you saying that to compare the modern day violence of Islam to Christianity you have to go back to the 1100s? Ipso facto, Islam today is where Christianity was a millenia ago? If I were a liberal, I'd say you were racist!
