Turks came here in the 60's and 70's,you are comparing apples and oranges.I think that Turks in Europe would have integrated much better if it was not for the wave of migrants from Africa, Middle East and Asia that flooded Europe lately, which created hard feelings towards everyone non-European, and especially from an islamic country.
And who accepted all those migrants from Africa,Asia and whatnot with their strange cultures,and who let them keep their cultures and habits instead of integrating them into society?
In the UK they created a different society with their own customs clothes culture etc,in Belgium(Brussels),you cant enter certain neighborhoods as a native,in Berlin try going to an Arab(Palestinians,Syrians,Iraqis) neighborhood as a none Arab,in France whole cities have changed to Africa.
Who did all this?
Turks were all modern in the 60's 70's 80's,it all started from the 90's on when all the rest started coming and fucked up the whole system.
Again,who's fault is that?
