Trump's ban on Muslims

[Mister Agenda]

It's stochastic. We don't know (yet) who will be radicalized by a particular event. We can only reasonably conclude that some people on the margin of being radicalized will be tipped over the edge. Like economics, all the action is on the margin: our actions most affect those already primed for radicalization, whether to tip them over to radicalizing or to bring them back from the brink.

If the margin is that thin, barring people from that region probably isn't that awful an idea.

It isn't about 'US is good' to 'US is bad.'  It's 'US is bad' to 'We should catch some journalists and saw their heads off on the internet.'

Maybe I just have more faith in the general muslim than I should.

There are people on the margin of everything, Muslims aren't special in that regard. There are plenty of people on the margin of becoming violent in the USA, if they're pushed a bit. Many thousands of them murder their fellow Americans every year.
