Slavery and genocide are comparible with regards to human freedom and liberty. Both crush all notion of such in the most absolute ways possible. Nazi labour camps ensured Jewish people and others were worked until their bodies were useless. It was an insustainable model and made purposely so.
American slavery adopted a sustainable model instead that was no less inhuman. Slaves were bred like kennel animals for generations. They were crossed without any thought to the notion of family or upbringing. Strong was bred to strong in hope of creating stronger and the bloodline of those people were altered for all time. Healers, artists, and teachers were not allowed to pass on their knowledge. The healer was to sire an ox, the artist an ox and the teacher, more oxen as well. Entire tribes and people were given over to husbandry and manual labour from childhood to death. It's miraculous that anything from their cultures survived that particular dark age.
To even consider a single life given completely over to the thankless toil of slavery is a challenge to even an imaginative mind. I have learned through experience that to consider the age of slavery and the misery of untold millions is something that the white brain is incapable of fully accepting. Society has created many vents, many safety valves to turn so that none feel too uncomfortable when pondering this history, this reality. Evidence of this permeates the thread. "Why can't we all just move on?"
It seems many you already have, so why ask in the first place? Just leave and be done. It is after all the doom of men that they forget.
