> Plenty of third generation Turks still don't consider themselves German, then someone with black skin adopted as a child might consider themself German
You seem to exactly know what I'm babbling about. Parent commentator somehow confused "looks like" for "is citizen of", something you seem to grasp perfectly well.
For all we know, 100% of the people the parent saw were actually "Young Germans", as you cannot tell people's nationality by just looking at them. Unless of course, "Young Germans" is actually referring to something else, not people's nationality.
