> It's not just about the deaths, but also about the suffering and degradation spanning generations, for the sole purpose of making "superior people" more money.
Absolutely, I don't see anybody making the claim that slavery is wonderful, and devoid of suffering and degradation for generations to come. Maybe the folks walking around with tiki torches, but, let's be real. You and I, and most of Hacker News interlocutors are not spending much time around that crowd day-in and day-out, so we can all safely assume nobody is advocating for that here.
The fact however is that slavery has been with us, as a species, for the entirety of our recorded history, and is still alive and well as of today, in one form or another. As horrible as the Atlantic slave trade has been for centuries, we can learn more history, transcend a US-centric, exceptionalist world view, and realize that what we're talking about was not an isolated, special and rare phenomenon, never seen before, or that never happened again since.
