The world, particularly the USA, is drowning in slavery myths. Being a slave may not have been the most pleasant life, but it was arguably the very best life a nigger, by it's inferiority, could hope for.
I wonder what the average life expectancy was for the average nigger in Africa, during the time of slavery? Why do I think those disease ridden, primitive things, lived longer and better as slaves? With the nigger African unable to record anything in writing, I'll likely never know. Whatever records of such matters will have been recorded by humans.
Slave abuse? I'm certain some amount of that went on, but let's be practical. The nigger slave was cattle, a piece of equipment to be used by humans. What would have been the practical or financial motivation for all of this alleged abuse? Slave owners would not have done well by having their niggers "in the shop", inoperable.
Do people beat on their horses, cattle, goats, routinely? Of course not. They'd destroy their own livelihood. In the case of the nigger, that rational would have people draining the oil from their tractors and revving up the engines until they exploded.
No doubt, some niggers had the shit kicked out of them for being a useless burden, but that had to be a fairly rare exception. A smaller portion of niggers, due to their crimes or behavior were "put down", I'm certain. I seriously doubt that the owner got any financial gain from that and those were reserved for serious infractions.
I really don't know the purpose of niggers on the planet. We certainly would have done well to let these things be whatever primitive, purposeless animal that they are. We've paid very dearly for trying to find a use for them.
Left to what they are is Aperica in it's full glory today.
Cattle with opposable thumbs didn't play out for us as well as our ancestors thought. In their defense, our ancestors would have NEVER believed that we'd have let these loose on the population.
