I know a woman who was married to a muslim. She is adamant that they all believe in Sharia Law.
When they are few they will be as nice as can be, the perfect neighbors and co-workers. When they are many, they become vicious tyrants who will do ANYTHING to advance Islam, including murdering, raping, bombings, and terrorism.
She is right. They believe in Sharia Law the way we believe in the Constitution. Some may be stricter in its interpretation, but they all think of it as the ultimate authority to follow. Even moderates can’t deny that it must be followed. There is no way around it, it comes direct from Mad Mo and the Moon God.
