The same sort of absolute submission required by our Lord in order to enter the Kingdom of heaven? As revealed in the Book of Revelations?
The Islamics want everybody to submit to them. Whoever opposes Islam must 'submit or die.'
Put another way, surrender and convert to Islam or be beaten, raped, tortured, beaten, and raped, over and over, then they will kill you slowly. All non-Muslims are viewed as non-persons. This is a spirtual world. To the Muslim, you have no existence at all, exist only in a dream, therefor, you may beaten, raped, or murdered at their will.
Arabs are famous for torturing Christians and Jews to death with 'the thousand cuts of Allah,' Meaning they enjoy slowly skinning their victims alive. Finally, at the end, after hours of torture, they cut off your private parts and insert them into the victim's mouth.
Islamics believe they are being much more gentle when they blow you up quickly with a suicide bomb.
Any nut who substitutes religious quotations for reasoning and thinking is simply that: a nut.
I have no use for any of them, regardles of which book they are using.
