The difference between Eastern Europe and some parts of Africa is that there were no apologies or reparations of any kind until now.
Not to mention my post was also about mongols, ottomans, and Soviet occupations.
We can talk about other incidents you think are similar in nature and how we should deal with those. Multiple things can be bad at the same time. Can you be any more precise than "the Mongols" and "the Soviets"? Which incidents would you like to talk about, who were the victims, what was done to them, who did it and who today do you think benefits/suffers from what happened?
