Perhaps you misunderstand.  I quoted from his article and added the capitalized words to set things to the proper perspective.
Left alone, the author would have us believe that all Muslims, those already here, even citizens, would have to prove they aren't terrorists or terrorist sympathizers.  That's just false.  As to how a would-be immigrant or refugee from hotbeds of terrorism such as Iraq, Afghanistan etc. would prove such a thing is irrelevant to me as I am more concerned with protecting the citizens of THIS country.
