Once in school, as a young boy, I decided to meet with an African woman, who I liked to the damn, and invited her on a date - she said that she does not represent us together, because I am a white and also with Soviet-Jewish roots a godless. I was so offended that I told her very loudly in the face that she was a racist and a Nazi and had no right to humiliate me with my white color of skin and my country of origin. This was heard by our cool leader and the girl received Verweis (a type of excuse) for intolerant attitude toward other peoples and beliefs.
After that, my friend, the German, joked that he was shocked by what he saw as a Soviet Jew was able to call a black refugee from Africa racist on the territory of the former Nazi Germany, and also to punish her for being intolerant to himself.
It was long ago. Everyone reacts differently to their first failure with the other sex.
If anything, I am still ashamed :) All good :)
