This proposal by the orange Pillsbury boy to our south is offensive, yes, also so ridiculous as to be unworkable.  How, precisely, is any security screening to determine who is Muslim and who is Christian?  He's not offering refuge to Jews under persecution?  What's with that?  It is not possible to tell if someone is Christian or Muslim by simply looking at them. There are many Lebanese Christians (Danny Thomas and Jamie Farr are two of many examples of Christian Lebanese Americans).  One can't even tell within North America who is a Christian and who is not.  Many sincere Christians do not attend an organized church because they find many to be businesses more interested in securing their financial bottom line than in helping people to connect with God.  Perhaps Trump and some of his fellow Republicans in the Senate and in the House consider themselves to be Christians? Actively seeking to withhold access to quality healthcare based on income is NOT consistent with Jesus' teachings.
