Whether or not I always agree with them, Paul McCaw's opinions usually supply food for thought. That said, I would like to chew a bit on his claim that Sharia law is not a potential threat.
He wrote, "Otherwise rational people (are) afraid that Sharia law, if it ever became part of our legal system, would allow men to murder their wives and daughters." (There's nothing to fear from Sharia law, Dec. 28.)
Many Americans rely upon Wikipedia or on benign statements by Islamic advocate groups such as Council on American-Islamic Relations for information regarding Islamic law. I recommend a study of actual authorities on this issue that do not sugarcoat it for Western consumption.
Read the 1,232-page "Reliance of the Traveller, A Classic Manual of Islamic Sacred Law" by Ahmad ibn Naqib al-Misri translated by Nuh Ha Mim Keller in Arabic with facing English translation (Amazon has it).
Sharia, based upon the Quran and Hadith, encompasses much more than civil law and is intended to govern every single aspect of human life. One will find four pages (75-79) depicting in great detail just how one should "go to the lavatory" including admonitions not to allow the "frontside or backside to be positioned facing the direction of prayer (Mecca)." Yes, there are various degrees of it observed among numerous Muslim nations but no form of it should ever be allowed to substitute for U.S. law that is based upon our secular Constitution, Bill of Rights and U.S. Code.
I've seen Sharia law in action and its impact upon society -- especially upon women -- having observed it in Saudi Arabia and also during a two-year ringside seat in Khartoum beginning soon after Bashir's June 30, 1989, military coup. He, along with Hassan al-Turabi's National Islamic Front, suspended political parties and introduced dictatorial, theocratic Sharia. Forty to 80 harsh lashes for drinking a beer isn't funny.
Our laws aren't based upon beliefs of this or that prophet whether Muslim, Jewish or Christian, but on our secular Constitution, which includes a wall of separation between church and state as described by Jefferson and Madison.
Professor Abdul Hamid abu Sulayman wrote in The Islamic Theory of International Relations (another interesting read), "Shariah is the divine will revealed to the Prophet pertaining to the conduct of human life in this world."
We don't need that particular camel's nose under our constitutional tent.
