How would you tell the difference between the ideological muslims and the non-ideological muslims?
Simply put with an interview with the right questions asked by a competent, knowledgable (hard to find) immigration officer and accurate background information. Within 24 hours I can usually discern what a Muslim believes about Americans and about the west in general. I am not convinced (yet) that all muslims are committed to the destruction of the west. There are plenty of them that are persecuted by their own - Kurds, Sudanese Black muslims, Shiias from iraq, etc. These I see as potential converts to Christianity.
By how tightly the tablecoth is wrapped around their heads?
