I would not be opposed to allowing Syrian and Iraqi Christians come here. These people are being subjected to genocide. I'd even sponsor a family and let them stay in my home. But I strenuously oppose allowing even one more muslim of any nationality enter thsi country for any reason.
If we could know for sure, I’d agree. But the problem is that I dont know how you tell the difference between those that are Christian and those that might be sleeper terrorists. Keep in mind that if in the service of Islam it is perfectly acceptable for a muzzie to lie to an infidel.
