What is this “real” history?
Thought that was already clear---yes, 150 years ago americans had slaves. Many white slave owners didn't like slavery but couldn't afford to get rid of their slaves---and many slaves couldn't survive without slavery. Like the plantations or not, being kicked out of the house with no food, no job, no medical, and no home would have been a nightmare for the slaves.
White america eventually got rid of their slaves...even forced the Indians to give up their slaves followed by going to africa to try force them to give up their slaves along with doing the same thing on island nations and south america. Even forced Japan and other nations to give up their slaves as late as WW2.
For all the slavers out there---Africans were the worse both in Africa and here in the Americas..the most abusive and never have I read of them freeing slaves...while whites on the otherhand did free slaves and even provided homes, lands, and other provisions needed to support themselves in large numbers out of conscious. Whites often treated slaves as indentured servants or better (pre-america and american whites provided lands and provisions for freed indentured servants by law and in many cases did the same for blacks that they freed out of conscious or pushing from their churches). While many many other white slaveowners did not want slaves but could find no way out of owning slaves either for their own financial safety or because they could not provide a way for the slaves to support themselves.
There was always a large percentage of free blacks in america. Many who then chose to buy slaves themselves.
Americans owning slaves was an odd thing not what the race pimps paint at all. Slavery in america by whites did not always exist as most envision. It came about mostly as a desperate shortage of workers that even indentured servants couldn't fill and was justified by whites (who found the notion on some basic level loathsome for the most part ) based on religion not skin color. Those pushing for slavery justified it as a way to save the souls of the unchristian heathens by conversion during slavery. It evolved from there to those that came from lands that weren't naturally "christian" which was all african countries even if the african had converted or his family had converted even before slavery...ergo all shipped over foreign blacks could be made slaves especially if they weren't christian. Black slaves had more value than white indentured servants btw, and as evidence by graves dug up in modern times---black slaves were generally treated far better than white indentured.
Many Christian sects were against slavery and pushed their parish to rid themselves of this sin. Many who inherited slaves didn't want slaves feeling that it was immoral and an abdomination against God and humanity. Practicality set in though---how do you survive if you give up the slaves and how do the slaves survive with no concept of freedom or supplies or home to support them. These slave owners had a conscious and weren't sadists out to torture their slaves---the assumption that they would go out of their way to harm their slaves is ignorant of the facts or wet fantasies by idiot race pimps like super who project their depravity on others. Those with a conscious would not enjoy harming others. IN many cases, white slavemasters' slaves were treated as atleast as pets, workmen, or even extended family...even at times as spouses which left many many biracial children to several owners or other whites related some way to the household who actually acted to protect and provide for their biracial children. And no, many of these kids were NOT the product of rapes---but of two willing people choosing to have sex. Many churches (which doesn't include the slaver church of the catholics) were against slavery and acted to help the slaves where ever they could---many churches pushed while others demanded that their parish members release their slaves while others acted to prevent slave owners in the community and elsewhere from extremely abusive behavior.
Blacks in America and In Africa on the other hand----almost always were more abusive than the guilt prone white owners. Many whites were abusive, but not all especially among the non-catholics and in most cases not as absolutely vicious as black slave owners were and are still till this day. If the race pimps want to beat up little kids conscious's over what some whites did over 150 years ago---then I think all the kids should start hearing about what blacks did 5000 years ago, 2500 years ago, 150 years ago, and still do currently to abuse people in a much larger mass.
