Let's see... You're on about Turks specifically, so I'll guess that you are German.
What is it now, fifteen million unassimilable Turkish muslims in the last fifteen years? Yes, I'd say that Germany has a problem of its own making. Suddenly the multicultural ideal doesn't look so rosey does it? Well it isn't as if some realists didn't try to warn you.
Then there's France, being set on fire by about 25 million Algerian and middle eastern muslims who don't give a rat's butt about learning to become frenchmen. There's the Netherlands, whose muslim population busies itself murdering politicians and film makers, and trying to impose sharia law in Amsterdam. There's Denmark with its cartoon riots. There's England, probably the people most alienated in Europe from their culture and history. I suppose that I'd be pretty alienated too if my country had gone from being the greatest empire in the history of the world to becoming a second rate American dependency in a single generation. Now England is overrun with muslim supremacists and suddenly the English are too cowardly to so much as discipline their own children.
Europe Died in Auschwitz just like the Jews did. The Nazis murdered the intellectual cream of Europe while Europe and the rest of the world stood around with their thumb up their collective butt. They traded those Jews for tens of millions of muslims who will never be Europeans. Fifteen hundred years of successful defense of Europe from Islamic evil, shot to hell in a couple of decades. Honestly, I have no sympathy for Europeans. They have turned their backs on their history, their cultures and on themselves. Hell, there won't be any Europe in a few more decades. She is comitting cultural and demographic suicide while her own leaders and American liberals applaud.
You don't have to rebuild the concentration camps. What would be the point of that? Europe could simply deport the lot, but she lacks the moral courage. At the very least, she could start restricting muslim immigration, but she hasn't the courage for that either. So long as this is the case, Europe has no future.
