And you know what, I agree with you to a certain extent (though I do find the feelings uncomfortable). I'm just not sure that a ban is all that useful or meaningful.
Hell, I'm not sure it's useful or meaningful either, particularly when it only involves seven countries. On the other hand, I do agree with the concept of 'severe vetting' for visitors from certain countries, and especially for immigrants and refugees coming from them. How would you vet them? Have the male immigration officer interview the wife - with no husband present. If they won't go for that then they're probably not the ones we want.
