This is an important point from Edward E. Curtis IV about sharia. Conservatives generally use the term exclusively to mean Taliban-style Sharia, but it's far more complicated than that:
In Islam, sharia ("the Way" to God) theoretically governs every human act. But Muslims do not agree on what sharia says; there is no one sharia book of laws. Most mosques in America do not teach Islamic law for a simple reason: It's too complicated for the average believer and even for some imams.
Islamic law includes not only the Koran and the Sunna (the traditions of the prophet Muhammad) but also great bodies of arcane legal rulings and pedantic scholarly interpretations. If mosques forced Islamic law upon their congregants, most Muslims would probably leave -- just as most Christians might walk out of the pews if preachers gave sermons exclusively on Saint Augustine, canon law and Greek grammar. Instead, mosques study the Koran and the Sunna and how the principles and stories in those sacred texts apply to their everyday lives.
Of course, since 9/11, every single conservative blogger on the Internet is an expert.
