On the Fact that While Human Migrations and Colonization Are as Ancient as Man Himself, it Also Must Be Stated that Not All Such Patterns Have Been Welcomed by and/or Beneficial to the Indigenous People (the Muslims Moving Into Spain and India, the Europeans Moving Into the Americas and Australia, etc.)

So, yeah, maybe all of these Western nations need to slow down a little to see if the folks who are currently bum-rushing into their countries a) can be assimilated and b) don't mean them any harm...….and to do so before they reach a tipping point because by then a reversal of policy may not be feasible (absent a war, that is).
