James Mixon,
But my question why continue to hold on to Sharia law when it has devastated your country?
There is a very wide range of Sharia law from country to country. There are different interpretations of it amongst Muslims. It is not a standard code of laws and they don't all fall into the radical conservatism of ISIS, Al Qaeda, etc.
In any case, I am virulently anti-authoritarian in matters concerning religion and the state.
