You’re talking about prison convicts right? Actually lookup “chattel slavery”, it means someone owns the person. No matter how you spin the words to make yourself right, convicts don’t have owners. What they do is involuntary servitude not slavery. Calling it slavery devalues the experience of people who were forcibly kidnapped, shipped across the ocean, and sold in markets. And no, the race disparity in prison populations doesn’t make prison labor slavery, anymore than being green makes grass a frog.
