Sorry, but I think you completly fail.
I bet 80% of the turks living in Germany have the turky flag on RHI - and it's good!
It's just that (not all, but most of them) react in a way different then people who were growing up here, with German parents.
I'm NOT racist now at all - it's just a fact. Trust me, i live here for many years. Yes, they have the citizenship of Germany. But when I had to go to Norway, Denmark, England or what else, I still would be have my German style to life and THATS the important thing.
Just let the people represent themself how the feel, not where they're from.
