Well, first of all, the Divine Right of Kings is neither a political system, nor has it been extant in at least a century.
And I am not gung-ho for Islam
Secondly, you might -- if you agree -- realize that allowing Islam free reign over here will result in some severe problems. Islam is a political system that has a religious component.
If a powerful church says that a king has his rights because God says so, how is this not political.
I have no desire for Islam to have free reign in US politics. In fact given the kinds of things (hatred, etc.) the Wahabbi oriented/Saudi financed mosques are reported to be teaching in some places here, I wonder why they are not being charged with contributing to the delinquency of minors.
