Years ago a Muslim US citizen spoke on a local late night "new age" radio talk show - to share the benign parts of his faith. I called in and asked him what he would do if Salman Rushdie, the author of "Satanic Verses", appeared on the street near him.
The Ayatollah Khomeini had issued a "death fatwa" on him for blashemy, supposedly binding on all Muslims.
He admitted that he would have to kill Rushdie, even though that violated US laws. He thus declared that his allegiance to Islam trumped his allegiance to the US.
I propose that we pose similar "what if" questions to Muslims seeking citizenship. Some might answer truthfully, eliminating themselves.
Well I guess those with designs on promoting anti-western values, much less Islamic terrorism....... would never lie on an immigration form.
