So, your experience is that everybody including yourself can be a xenophobic?
Also, your experience is fitting to the legends of neonazi organizations, but completely contradicted by studies about the reality of the people. That the first generations had been working pretty hard in Germany, and have been often better integrated than the second or third generations is a fact. That the education of them had been poor is also a fact, that is why we brought them here. But still, you paint with such a broad brush about them, that it looks like you think your limited knowledge is the truth.
Did you ever talk to the Turks? How do you know that they are turks in first place? And what the hell do you know about body language?
Also, did you know that most unemployed with "immigration background" are actually from eastern Europe? People all complain about turks, but in reality, they only take the turks as projection of their hatred of other foreigners, because it is easier to rant about a Mr Özil, than about a Dieter Müller from Kiev.
Sorry, but many people are actually just garden gnome Nazis. They rant about foreigners, without even knowing anything about foreigners in Germany. They rant about them because others rant about them, because the Bild tabloid rants about them, and because nobody in their social neighborhood has a foreigner as friend who would step up and say "Shut up talking so badly about turks! My friend Erdogan works with me in Germany since we had been apprentices."
And it is so easy to complain about criminals with "migration background". if two germans are beating up homeless, the Germans are just victims of the system, or the homeless was likely guilty himself, there must be a reason why he is homeless. If the two Germans had Turkish grandparents, and their parents running a successful business as lawyers in Germany, they are genetically criminal and should be send home to Turkey.
It is pure bigotry. Please think twice before you become a bigot yourself. Even my Grandmother, who was pretty xenophobic and had all the "good" reasons to complain about foreigners, had been able to respect them and treat them as citizens. She did not feel well in their presence, and she admitted it, but she knew that her bad feelings are not because of the person in front of her.
