Sorry Levi, you have the wrong interpretation of Shariah law. Muslims can't just "drop it", Shariah is Islamic Law, it governs everything a Muslim does, in every aspect of their life. You can't separate Shariah from Islam, it doesn't work that way, Islam is a way of life and Shariah guides it, you can fragment it and hope to understand it. What you're suggesting is basically what extremists do, they separate and focus on aspects of Islam individually and in isolation for their purposes. It's not an interpretation, it's a bastardisation. The principles of it stem from the Wahhabi movement of the 17th century, which is not spiritual in it's principles. Islam is holistic, it has to be taken in it's whole, or not at all. The basis of it is spirituality and mercy.
