You have a poor understanding of what Sharia law is.  Sure it can be used in a conservative way to impose draconian viewpoints like the conservative groups known as the Daesh, and the American supported Nusra Front, but properly interpreted it can mean giving to charity, respecting your neighbours, following the law and caring for your fellow man.   You wish to interpret it in a conservative Old Testament (Hebrew Bible) way like "God is with us as we go to war and kill other nations".   Look at some of the Evangelicals who would kill homosexuals for their own good.   Tell me a difference.   Why not choose to interpret it as intended to help humankind
