These were what made slavery POSSIBLE.
The natural instinct is to try and appeal to how the slaves were TREATED by their masters.
As if this was the big bright ethical line.
Like slavery is bad but they maybe had casual Fridays?
(you could totally buy Black humans, but they weren't cheap.)
As if only being able to afford owning one human made an ethical difference
Without that violence, the "nice" slave owners couldn't BUY anyone.
Slaves stayed to not die.
