One wonders how hard he fights, and what measures he'd be willing to take to keep terrorists out of refugee camps in the middle east?

I say that not to be snarky (honest), but to raise the point of just how tricky this issue is.  The simple truth remains that the US has the largest annual legal immigration totals in the world.  That suggests a rather "generous" country in many ways.  So perhaps THAT should be a more fundamental question here: what IS the right level for immigration in the US, and why?

The ban is NOT against all Muslims, nor all countries.  We can (and often do) debate the wisdom and politics of it all, but the simple truth is that a ban like this reflects the fears of the people who live here.  Telling people not to f ear just doesn't work.  You can't mandate something like that.  Of MUCH more significance, is that despite the noise, this "ban" is relatively short term.  So perhaps energy would be better spent on getting to the underlying issues and fears?
