Foundation of Islam is synthesis between terrorysm and governance on practcal scale and east west ideology on religion aspect. Quoran is synthesis of Rigved and Bible stories.
Mongols accepted it because it allowed them to have more than one women in their Harem and 72 of them after they die. You see, after all mongols were blood thirsty but very practical people. Why they should become hindu or budhist or othe kind because there is no fun in it. After havibng fun for time being, they soon run out of women and men and had to come up with a new version of Quoran-Medina version that allowed them to rape and murder as they like including muslims that do not agree to their brand of Islam. In fact more muslims are killed by moslems then any other people. Guy who wries about injustice to muslim needs to have psychiatric consultation and get some psychotherapy.
