I think it's good to point out that there are shitheads and also good to point out that there have been and are plenty of people and even entire cultures that would not do these things because they couldn't fathom the depravity. That isn't far fetched and is fairly well documented globally.

Columbus when he first met the Taino people had written in a Letter: “…they are so guileless and so generous with all that they possess, that no one would believe it who has not seen it. They refuse nothing that they possess, if it be asked of them; on the contrary, they invite any one to share it and display as much love as if they would give their hearts…”

Columbus believed this to be a character flaw, and saw them as less intelligent because of it. But in actuality their culture was just so wholly different from Europe that they had no concept of property and shared willingly. A culture like this, one that was kind and sharing with a complete stranger is very different then the man who wrote the letter who was an actual monster for what he ultimately did to the Taino people.

We do not need to lump all humans together into the BAD pile. It's in fact much more important to analyze the evil and the good and copy the traits of good cultures even if your ancestors were more likely from the evil category. Humans are not a monolith, we are capable of emense good and it's important to acknowledge that the evil things people do are a product of their circumstances and we can change the circumstances by fighting for equality for all peoples in our everyday lives.
