As usual you are wrong. Let's discuss prejudice. You stating there were no successful civilizations anywhere colonialist went and that what they brought to people was better than what they had. That is the expression of a white ring whackadoodle. Look at what your people did... they go to zimbabwe and take land from people and make them second class citizens and slaves. Then alter the education of these people's children and yell them all the great monuments that their own people built were actually built by Europeans because africans were not smart enough to have done these things.
This was institutionalized white washed revisionist history. It made people forget centuries of their own accomplishments and made them feel that they were subhuman.
Your mom's take on the farming issue was also foolish. The indigenous people there were local farmers providing for family and tribes and small markets. White farmers who raped them of the land had a goal of mass farming with yield being the only concern. After all these people farm the land for centuries prior to your arrival and they were fine. Again it was colonialist greed that made it a problem.
Now let's talk prejudice. My best man in my wedding is white. My current neighbors who we go on vacation with are white. Etc... they are also well aware of my feelings and realize that I am informed and not a racist.
You on the other hand grew up in rhodesia which like Congo was governed by a bunch of racist Europeans that believed in wholesale killing and it seems you are in agreement with those actions.
Why would you ignore the facts about Leopold and congo? Based on what you said what he did was better for the land of Congo because they were just tribal pwople.
Explain how an invading European force Killin 15 million of 30 million inhabitants of a country is better for them. You can always just ignore that again or wait for someone else to support you with more exciting news of how africans and indigenous people of the Americas were just savages that needed to be colonized
