In free democracies, governments are accountable to the people and serve at the people’s pleasure. In Islamic theocracy, governments are accountable only to Allah and the people must serve at the pleasure of the government. And one can see the result of Islamic total or partial rule in fifty-six or so countries which rank among the highest nations of the world on every index of misery.
Other problems arise. Liberty, deeply cherished by democracies, is replaced by submission—unquestioning obedience and adherence to the dictates and precepts of the all-knowing and all-wise Allah. The individual becomes little more than a passive obedient vessel of Allah and his perspective of himself and life drastically changes. Once he submits to the all-powerful, all-knowing, then he is absolved of the responsibility of having to chart his own way in life.
It is this total form of submission that, among other things, prompted the Muslims to systematically burn libraries of the lands they invaded. They justified their actions by contending that the Quran, the comprehensive unerring book of Allah, contained all perfect knowledge that humanity needs. To this day, in places where Islam rules, many books are banned, newspapers and magazines are systematically either censored or shut down, and other non-print media are methodically blocked.
This, folks, is why Islam is incompatible with freedom and civilization. Period.
