Gotta run but before, I want to submit this link: An excellent NYT journalistic study that, as they write, looks at "integration from all sides" in Germany.

The storied city of Weimar, Germany (population 65,000), absorbed 900 refugees in a year. Our journalists spent months on the ground examining integration from all sides.

“The whole thing is to have power over women,” declared Mona Fofie, 24, speaking of the Muslim head covering called hijab.
The Syrian man, one of 900 asylum-seekers welcomed in Weimar, Germany, was no less upset. “Have you asked them?” demanded Anas Alkarri, 28. “I think you will find it is their choice to wear the hijab.”
She pressed on: “I have heard that women can’t worship in the mosque. Is this true?”
He scoffed: “Of course they can worship in the mosque. This is a misconception. There is a separate section in the back for them.”
The German woman stifled a gasp. “A separate section? Oh my God.”

So it went in a four-month cultural crash course pairing Weimar residents with refugees, and in informal interactions around the city and the rest of Germany, as roughly one million people arrived in galvanic waves from Syria, Iraq, Afghanistan and elsewhere. The rapid influx shook European social structures, accelerated a rise in right-wing nationalism and saddled social welfare systems with the complex challenge of absorbing so many desperate wanderers at once.
