Case in point, when a Roma family settles down, they can in theory just be another Eastern European family to those who don’t know their background. 28 years since the Berlin wall fell, Western European people are now pretty much used to mingling with Eastern Europeans.

I don’t think Syrians who stay will have a much different fate 20y from now.
