YES, this exactly the policy all non-Muslim countries need to adopt to bring a screeching halt to the building of Mosques outside of the sandbox. And voters here in the U.S. should DEMAND that the Presidential candidates of both parties go on record NOW in support of this policy. Let’s all attempt to get this demand jammed into the ears of both candidates and request an immediate response from them.
Not sure how accurate this is, but I believe there is usually a direct correlation between the absence of Mosques and the absence of Muslims, AND the absence of Islamic terrorists.
Such a policy will not open up the freedom to build churches in Muslim countries. That is not just going to happen. But what such a public policy would do is highlight the true nature of Islam where they come into power.
