It seems like an interesting religion and soothing to those who CHOSE it. I don't understand how Islam requires the follower to force people to convert or die. That isn't a choice, it is duress. And it doesn't work. Just like the Inquisition didn't work.
I think anyone should believe what they want. I can't even describe how I think of God, so I think we should tolerate others, but others, should also tolerate different religions, and beliefs.
