There seems to be some misconception about religion in the Caliphate so I am going to clarify things a bit^^

The Caliphate is a radical sunni Islamic state. There is no freedom of religion. The only option is to be sunni and if you don't want to you will feel the wrath of allah :)

Any other forms of religion are prohibited by law and their institutions dissolved between 2020 and 2035. There is no christian ortodox church, there are no catholic churches, no Jewish temples, no shia mosques. Also there are no religious minorities. They have all been persecuted, murdered, forced to leave the Caliphate or converted to Islam. Only a handful (less then two million) of non-sunni people remain in the Caliphate as slaves.

This policy of expelling all the other religions from the country has led to an unprecedent period of stability and prosperity within the Caliphate's borders. Sectarian violence has been eradicated by removing the competition. Women can go to the markets without having to fear getting blown up by suicide bombers. All the instability you see in present day Syria and Iraq has been gone. Everybody lives happily ever after under the sharia law, unless you're gay or commited adultry. Then you get stoned to death  ;)
