This is a Muslim ban - as long as it doesn't inconvenience citizens from countries with who/which Trump does business. The exceptions for Christians from the specified countries makes that clear. Both are described as being Roman Catholics. They should listen to their Pope rather than their President: Pope Francis made it clear that you cannot count yourself as being Christian if you support a Muslin ban. 

For God's sake, this stupid ban impacts the most vulnerable. It is immoral.
