Fair enough.
How would that work in reality. Ban all residents of majority Muslim countries? Ban all citizens of majority Muslim countries? Will it also affect transit passengers to 3rd countries? Would it only apply to people seeking immigration legally after landing in US?
What about the so-called moderate Muslim countries like Indonesia and Malaysia?
I think many who favor this don't realize the impact this could have, economically speaking.
I think Trump and most of those who support his plan would be open to reasonable accommodations. What we have now is not reasonable however, and Obama seems determined to make a bad situation worse.
The genius of Trump is that the discussion now is not about how many hundreds of thousands of muslim "refugees", ie economic migrants, we admit, but whether we can feasibly exclude all muslims or only the most problematic.
