Why are they still calling them migrants ? Someone trying to break into your home you would not call a visitor would you ? You'd call them a criminal. Someone trying to cross into your country illegally is not a migrant. These people were refugees when they landed in Greece or Italy. Possibly fleeing a war zone and possibly just trying to get to a better country for their own interests. If they decide to leave these two lands (which aren't at war or persecuting them) because benefits are better in other countries they then become illegal immigrants. Here we see the folly of open door ideals.
