More slaves in Central & South America than here. A lot more. But only whites were slavers, you’d think.
I think it’s part of the “neo-antisemitism”.
They observe that the “whites”, ie, those who follow Western Civ’s value system, tend to prosper,
and rather than attribute that prosperity to the value system (and adopt it),
they prefer to attribute it to an exploitation of those who aren’t as prosperous.
Not all societies that had slaves are currently prosperous, so that IS NOT the common factor, obviously.
