Wow, as a European that has lived in the UK and Spain I can categorically tell you that this 'no go zone' thing is BS of the highest caliber. And Europe is going to hell as much as the US and Canada is and it has nothing to do with migration, and all to do with neoliberal capitalist interests causing a banking crisis, a military occupation crisis and a crisis of community.
The only reason the nationalist elements are rising is because those that control the press (the same people that have caused these crises) are quite keen for the gullible to point fingers at 'the other' instead of a the actual architects of the mess this world is becoming.

Don't let the narrative hamper your ability to critically think. 80% of the stuff in the 'news' all over the world is bullshit and a lie can go around the world before the truth has put its shoes on.
