It’s a violent world-domination movement cleverly disguised as a religion.
There is NO direct equivalent of either the Ten Commandments or the Golden Rule anywhere in the Koran, and by its very declaration, the Koran supplants ALL other religious foundations from elsewhere.
The probable inspiration for the Koran may have been the Torah, or what the Christian religion calls the “Old Testament”, abridged and adapted to the peculiar mental condition of a sun-crazed old sand hermit. Parts that seemed too restrictive, or limiting, were simply dropped out, and the entire tract became a prescription for achieving a clear assertion of authority over those who were not persuaded of the rightness of this interpretation of a monotheistic universe.
In fact, the earlier writings of the Farsi religion of Zoroastrianism, which themselves were not all that different from the Old Testament, tended to this elitist view of divine right of the few to rule the many, but never was it expressed in such a bloodthirsty manner. But even that rather narrow interpretation extended the Golden Rule, or at least a negative version of it(One should not treat others in ways that one would not like to be treated), to all.
Islam restricts the application of its version to the Golden Rule ONLY to others of Muslim faith, and neither the Dhimmi, nor the Kafir is deemed worthy of the benediction conferred by application of reciprocity.
For Islam, the ratchet only works one way.
