From my time as an EMT, I always got kind of annoyed at the big porkers that we had to move, hurt my back once moving one. But then I’d get really mad at my collegues who bitched about and made fun of them, because you can’t leave a fellow human being in that condition, even if it is of their own making.
So I have no clue how I would respond to slavery. Pity? Anger? Disgust? Shame? Some of my ancestors owned slaves, several generations before the war.
As an American I have no frame of reference for slavery, because there is nothing in our modern society as repugnant as slavery. But then there’s that creepy feeling that if I was born and raised around it, it might not bother me so much, the way it didn’t bother 99% of society North or South that much. I like to think I’m better than that. But yeah, there’s disgust and shame.
