I don't understand how anybody can be against vetting newcomers and reducing or eliminating immigration from cultures known to be contrary to the beliefs and values of the host country.  That just seems common sense.  Yet reading some of these comments you would think we should open our doors for anyone to move here despite beliefs or skill sets, up to and including wanting to murder the people in their new host country.  Have people totally lost their minds or have they been brainwashed and PC'ed into submissions.
