Slavery existed in Africa but it was nothing on the level of the inhumane barbaric chattel slavery that we went through here where we were treated worse than animals.
Slavery in Africa was indentured servitude. You worked for free until you paid off your debts etc etc.
If, and I say IF, our ppl sold us to white ppl, they could not have known what we were in for once we touched down on America's shores. They had no way to know that we would be raped, brutalized, etc etc. They thought it was the same as slavery among black ppl in Africa, where if someone was your indentured servant, you could trade them between each other.
I'm still saying IF though, because I honestly do not believe that our ppl sold us to these devils. I think that's something they made up.
