In the midst of an otherwise testy press conference this morning in Turkey, President Obama eagerly denounced the calls from some Republicans to limit the entry of Syrian refugees to those who were Christian. The president asserted, “”That’s not American. That’s not who we are. We don’t have a religious test for our compassion.” That sounds right and those, like Senator Ted Cruz who have advocated treating Middle East Christian refugees different from Muslim, have taken a stand that sounds like discrimination. Yet while religious tests are wrong in principle, Cruz understood a factor that Obama ignored about the nature of the mass of humanity fleeing the chaos and violence. But even Cruz was missing the point that is underlying the reluctance of many Americans to take in even a small percentage of the millions seeking to get away from an ISIS rampage that Obama seems unwilling or unable to roll back.
