Well imagine a large group of christians with very small minority of muslims among them.
There are well over a hundred Christian nations in the world and in everyone of them, Muslim minorities are living peacefully, without facing any persecution. But the reverse is not true for any of the 50+ Muslim nations.
Side note: The Islamic "Caliphate" represents a sort of religious Utopia. Men have conceived of and written down rule sets for many utopias, I have an entire book on these concepts. None of these have ever worked, and none of them ever has.
If we conceive of the "Islamic Caliphate" as a flawed concept, although well meaning, of a utopia, then the matter is clarified. The Muslim nations attempt to implement their utopia, and the nations and the people then suffer.
