Would have been better if it were an example that Anathema held....
Or at least more recent in modern usage.
I'm not well versed in the pro-slavery arguments of the day. Mostly from what I've heard they were "shit talkers".
You’re proving the point.
You say you're not well-versed in the pro-slavery arguments, but that’s exactly the problem. People who believed in it back then didn’t walk around thinking “we’re the villains.” They thought they were defending order, tradition, faith, the family structure; the same pillars people still invoke today, just under new topics.
They weren’t “shit talkers.” They were legislators, preachers, professors, and neighbors. They believed they were on the side of good. That’s what makes moral certainty so dangerous. It doesn’t feel evil. It feels obvious.
You asked for a concrete example. I gave you one. Now you're shifting the goalpost by saying it’s too old, too far removed, but if the principle doesn't hold up over time, it was never a principle; it was a mood dressed in tradition.
So let’s bring it closer...
Interracial marriage was illegal in parts of the U.S. until 1967. The moral arguments against it were biblical, traditional, and "timeless."
Women couldn’t vote until 1920. The argument? It would disrupt the natural social order, and that men were better suited for rational decision-making.
Gay marriage was opposed by both parties for decades using appeals to morality, family values, and religious certainty. It’s now legal, and the sky didn’t fall.
Each of these views was defended as obvious, righteous, and unchangeable, until someone questioned what everyone else called truth. That’s not ancient history. That’s your grandparents.
