Did you know there have been literal slave markets in the past? And they still exist today (e.g. in Lybia). Please explain how this is "not universally bad". Actually don't. Spare us your disgusting mental gymnastics that you shamelessly try to disguise as autism.
>Please explain how this is "not universally bad".
Lets say that you have a country where slavery is legal. The slaves of course don't like it. But lets say that the populace is largely in favor of it, because slave labor keeps the barebones economy going and people can trade and have food to eat. Most people don't actively capture slaves, they just buy them at the market.
If you had the power to eliminate slavery in that country, you would free the slaves, but you would basically condem a lot of the people to die from starvation.
So whats the "correct" moral stance? Real world isn't black and white like you would want it to be.
I am holding my finger on the nuclear bomb button and I say if you don't murder everyone except me and you, I will press the button and it will murder everyone including me and you. So what's the "correct" moral stance?
