The Islamic Leader doesn't know what he is talking about, and will be slammed by other Muslims for his stance.
Sorry, Noomi, as I know you have had a lot of negative responses but those responses are entirely valid. The islamic leader knows exactly what he is talking about.
Islam's history, literature and scripture is uncompromising in its hate for Jews, Christians and even competing sects of Islam. That has been the case from its invention. Islam's revulsion for competing faiths is a long and storied one.
If we look at events shaping the Islamist Middle East currently, what I come away with is just how fiercely and violently resistant the ideology actually is to any sort of reform or revision. This is its single most unchanging inability for coexistence with the rest of the world. We simply need to listen to what islam's Sheiks, Ayatollahs, Muftis, Imams, etc., tell us in clear and uncompromising terms that islam and sharia is held by Moslems to be the only legitimate system of law for all places, for all of mankind, at all times. By both actions and words, Moslems tell us that they are absolutely convinced that their religion must be imposed on all for all time. That is the foundation of its intolerance and contempt for all other worldviews.
