I keep hearing this, but these people were all vetted. No one was just casually entering the US from these countries. It isn't like we didn't know there were risks from these countries before, hence why Trump is touting he's using the same list as the Obama administration. And not letting in refugees makes zero sense - they're vetted far more extremely than any other entrants to the US, we're basically only taking women and children (no single males), and we were taking essentially a handful a year. Plus, WE choose who we take as refugees, refugees never get to choose what country they get to go to. We have always done so. They are always vetted very carefully before we allow them. The Trump administration has given zero indication as to what "extreme vetting" even means. He sells fear, and people buy it. Facts are more powerful than fear.
