I think that we nay have been here before. The nature of Islam is submission to Allah (God) as laid down in the Quran (which may not be altered and should always be read in its original language as translations are frowned upon). Therefore Muslims are used to submission and listen carefully to their Imam. You will notice in pictures of Muslims at prayer you will only see men and they all do exactly the same at the same time and generally dress alike. Free speech and even free will which is more conducive to democracy does not greatly flourish under such circumstances. There are exceptions but ISIS wants to establish a caliphate who is lead by one supreme leader. Iran has something like that. A caliph is not far removed from a dictator, king etc.
