I would like to present my opinion and facts that I have gathered.

I'm in no way racist, but I am very well aware that no black-Germans exist. I say this because you are either German or you're not. Slavic mix with German is practically, if not always, the same people from different tribes. Europeans. While Africans cannot be considered Germanic.

If this offends anyone I apologize, but Afro-German is just not an ethnicity. The German person is a white variant of different European "Tribes", yet he is European. A German, like a Yugoslav or a Hungarian, is a European. The same cannot be said for an African person. It is just reality.
If you like to discuss further, please reply and we'll lead a friendly discussion.
