I have to disagree with this notion, and it's something that is often trotted out as a reason that Islam and democracy cannot coexist. I've heard so many people say that Muslim cannot have a democratic system of government because people might vote to approve something which is un-Islamic. However, the solution to this is incredibly obvious: make a Constitution that says all newly proposed laws and regulations must abide by the shariah, and have a court system that could strike down laws and regulations that they deem un-Islamic. I just find this whole "oh but they could vote on something and make that which Allah declared haram halal" argument to be absurd. Well...so could any ruler! The difference is that if that ruler does such a thing, within a democratic framework, the people could simply elect him out of office or the courts could simply strike down his laws. In an autocratic system, the leader could do all of these things, and nothing could stop him other than a revolt, which of course is a horrible thing to occur within a country because it leads to economic stagnation and the purging of counter-revolutionaries--or if the revolt fails, simply quite a lot of dead people.
