Most Christians seem to disagree with you on this. They "KNOW" that god loves them and that Jesus is the lord and savior. Muslims KNOW that Allah is their god. People have killed in the name of their religion in the past and caused huge amounts of animosity in the world as well as forcing religiously based bigoted laws in America right this very second. That isn't because they "think" that there is something else afoot in some kind of harmless and passive way.

Well, gee, if we didn't believe that, we wouldn't even have a faith. If Muslims didn't believe anything about Allah, then could they even have a religion/faith? But, even so, it is still a faith and nothing we try and prove. There are a lot of laws that Christians had nothing to do with, such as abortion laws and having sex outside of marriage isn't against the law of the land, so I think you might want to rethink that:If you do, You may not change your mind and think that I am full of it, however. I am just saying that not all laws are religion based.
