I'm born in Germany, grew up there, went to school there, had german friends and learned the german culture. My dad is a white german, but my mom is from Laos and that's why I look like this (relax, it's not a pic of me). People in Germany don't believe that I'm german, even if I have a passport and german is my native language. *sigh*
Race-mixing is difficult, not because of "pure blood" but because for the children it's never easy then to feel at home somewhere.
