Back in the '80s, I produced several programs on slavery for public TV -so you would lose that bet. Black African inter-tribal 'slavery', where the losing tribe in a battle is integrated into the victorious tribes ranks as brothers and sisters is not in the same category as the inhumane industrial slavery visited on Africa by Islamic Arabs and White Christians.
You are confusing the practices of slave catching Islamic-Arabic Blacks, like the (Barbary Pirate) Berbers, Tuaregs, and Moors, -who raided the heart of Africa for gold, salt and slaves, with Black African customs. But, I imagine all Blacks, like the Arabic black in your graphic, look alike to you. In addition, Islam castrated captured Black African slaves so, with few exceptions, like Hejaz, there really are no sizable Black slave descendant communities in Arabic countries.
Slavery in the Americas was an especially barbaric industry rooted in the rape of women and sale of the children. This industrial form of branded breeding was so effective they banned the import of slaves nearly a century before they alleged to have 'freed the slaves.
Of course, the slaves were never freed in the humane sense of the word. They were released from plantation shacks like Free Range 'animals' are released from a barn. They are not Free. The conditions for their harvesting have simply changed. In this case, the Slave Patrols became the Police, who then took over the task of harvesting free labor from Blacks, through
The Black Codes -a book of absurd 'laws' -like walking on the wrong side of the street at the wrong hour, to scoop-up 'free range' Blacks and jail them.
In reality, the only thing that was banned 150 years ago was an individuals' right to own slaves. Slavery merely transitioned into a municipal institution.
Converted plantations became the 1st penitentiaries, and a Convict Lease System continued the American tradition of exploiting forced Black labor for White profit.
Again, while I know your heart is not in the right place, thanks for the opportunity to address issues most people prefer to ignore. But, I gotta say... their is no upside for you in this. Not compensating slaves, or their descendants, is not a winning argument. The whole
'they were well fed and housed' mentality is just another reflection of a denial infliction trying to avoid taking responsibility for a history of slavery.
It also puts the US on the wrong side of history. The only reason the USA is not paying for slavery now is because no country can hold it accountable. But, just as the US can use its might to arrest brutal dictators, drug kingpins, war criminals, etc., and charge them with Crimes Against Humanity, including child slavery, there are civilizations in this Big Black Universe more than capable of holding the US accountable for its Crimes Against Humanity and/or Crimes Against The Universe.
I write this not from a place of hate, but of love... as I Love White folks! And the full spectrum of humanity. But an 'advanced civilization' must actually be an advanced civilization if it expects to make CONTACT with Advanced Civilizations. Likewise, cosmic apes attract cosmic apes.
