What I find dangerous about this bill is it implies credence to perceived legitimacy of Sharia as an alternative to American law. A crime is a crime, no matter what religious flag you wave in front of your justifications. I would never legitimize Sharia by banning it because it already has no merit for proving for guilt or innocence when considering criminal complaints. Sharia is nothing but a shield for common criminals to hide behind and in my opinion has no basis in our court system for any purpose. If we ban it, it will be defended and if the ban is overturned (as our present administration would likely do), what is the end result? A stronger Sharia foothold in our court system than we started with? No thanks.
Put the scumbag in jail because he beat his wife, not because he did it out of his religious "principals".
A gun is like a parachute. If you need one and don't have one, you'll probably never need one again.
