The last horrific massacre that could be remembered by the entire mankind as a perpetual stigma is The Holocaust. That was before 1994. If there were millions of Orthodox Jews, Polish, and Russians slaughtered back then, it was the result of extreme bigotry and racism. The trouble with a single continent such as Europe is that there are far too many different cultures to tolerate. In Africa, there is little difference from one culture to the next. Yet, racism existed and resulted in another grand butchering back in 1994, called the Rwandan Genocide.
