This has been and will continue to be about culture.  Immigration (mass or otherwise) always is.

The Muslim and Judeo-Christian cultures are like oil and water.  A few decades of 'globalization' can't and won't change that.  The only issue at this point is that western society has 'matured' to a point where political (in)correctness drives the day, rather than trying to protect a people and their culture from upset.  So now we have people who value little apart from the generous social net of their now adopted homes, upsetting the apple cart.

The sheep here that bleat on about multiculturalism need only diversify their inputs to sources overseas.  Youtube videos of the carnage left behind by these so called refugees and you will see a peoples true character.  Look on in horror as you witness a muslim mob in a Swedish mall hang from and destroy the centre Christmas tree for no good reason....(your belief in things religious aside).  It's all about culture people.
