'Atheist Caliphate'?
Places of 'worship' don't need to be controlled per-se, they simply need to have all public funding and tax incentives removed.
If god wants it, then god can pay for it.
But do you accept any of the methods of payment God offers? He can write you a personal cheque for the sum of infinite love, or wire the light of belief funds directly into your disbelieving heart from his bank account in Nigera.
Either that or atleast provide a consistent definition of what their god actually is.
(If it knows and see's everything, then the building is irrelevant, if it predetermines our lives, then the building coming down is gods plan, if gods all powerful but doesn't defend against the removal of the building, then we'll take it as an o.k from it...ofcourse, all of those conflict with Islam because somethings only true when it supports their intentions)
Being serious for a second, I agree that religious organisations shouldn't get tax breaks. They should pay just like any other social club or association. Charity work should done separately through established charities for those purposes, which abide fully by rules regarding offering services to the public. eg. No discrimination against homosexuals wishing to adopt.
