Also inflammatory.
>Maybe some big attack is carried out by a radicalized Muslim from France or Sweden, and the response is to ban entries from there. I'd have called this idea absurd not too long ago, but now I consider this kind of thing a serious, if small, possibility.

Sorry to spend most of my comment criticizing your comment but I really cant stand this kind of rhetoric.
