Although I know from your comment history that the question is unlikely to be genuine: you do have a point that many Germans like to forget that the entire point of the Eastern Front was to create "Lebensraum" (living space), which meant depopulation (either via deportations or mass executions). Especially the Slavic population was considered "sub-human".
That said, most Germans aren't even consciously aware Germany ever had colonies or what that meant. The awareness of war crimes in WW2 is much more widespread, despite the concerted post-war effort to shift the blame away from the Wehrmacht (both by Germans and by the Western Allies who benefited from West Germany not purging its entire military as Europe entered the Cold War).
Without necessarily understanding every nuance and knowing of every single war crime Germany committed during WW2, Germans in general and the German government specifically have spent more than seven decades acknowledging the Third Reich's wrongdoings and contributing financial aid to various forms of reparation. Germans and their government have done no such thing for Africa: the exploitation and massacre of Africans is barely even taught in history classes.
