There are more than a few conservatives who only respect the constitution to the point where it interferes with their world-view. I had a drag-out argument a couple of nights ago with someone who believed the 1st amendment shouldn’t stop the federal government from banning the worship of islam and closing all the mosques, because the government should be able to define Islam as “not a religion”. Worse, for my defense of the 1st amendment I was called a muslim sympathiser, and told I was defending Sharia law.
Currently you are hearing the nuttier of the Imams telling folks that once they take over they will impose Sharia, and eliminate democracy. That right there ought to justify putting a bullet right between their eyes of course. At the same time it should justify a clause in the requirements for immigration concerning SUPPORTING THE AMERICAN FORM OF LAW AND GOVERNMENT and RENOUNCING ALL OTHER FORMS OF LAW AND GOVERNMENT.
Just modify the McCarren Act again.
We could use something similar when it comes to admitting Mexican government officials as "refugees". Remember, they have to take oaths that require antagonism against the Catholic Church. Not that I particularly care if anyone is antagonistic or not, but it's the oath part. The Mexican government agents trying to flee to the US should be required to RENOUNCE any such oaths ~ implied or actual.
