I do not  believe that anyone who opposes a country's leader be barred from entry. I merely suggested that anyone stupid enough to express such opinions at the border should be denied entry and that anyone who openly expresses opinions that could be interpreted as a threat to the government or elected officials of that country have their name flagged for future reference. Unfortunately, too many leftists are clueless. Their overwhelming sense of entitlement causes them to believe that they can express their opinions anywhere and anytime without consequences.
