Who said anything about Afro-German being a race?
Afro-Americans are not considered a race nor are Irish,Italian or Hispanic-Americans considerd a race.
What we are talking about is your cultural background, your ethnicity.
That is why they call it ethnic cleansing when one tries to be rid of people of the same race but of different ethnic backgrounds i.e. Serbs & Bosnians in former Yugoslavia or Tutsi and Hutu in Rwanda etc.
My Mother is Afro-German and my Father is Afro-American. That makes me Afro-Germarican.
Und ich bin Stolz darauf!
Auf Wiedersehen and Wilkommen im 21en Jahrhundert!
