Well...we could ask the Obama administration for the good reasons why those 6 countries are on the list.  Since, of course, that's the info given to the current admin from the previous.  "...other than they have lots of Muslims."  hmmm...so if I were in Oakland (Raider Nation Baby!) and it just so happened that all the police were black guys, would it still be racist if blacks (Oakland is 82% black, btw) were the predominant race that was pulled over, arrested, investigated, etc.?  Hyperthetics won't do it here.  Hmmm....Ok...as to if it makes sense to do it....I would say it would be better to stop Mr T from getting here first, THEN find them and blow them up ova dea, then to let them in amongst the legit emigrees/immigrants/tourists/whatever and have to root them out of our vast nation full of hiding places.  Seems more efficient to me.  And in the long term more effective.  I will ALWAYS sacrifice short term efficiency for long term effectiveness.
