Slavery has never been completely vanquished, certainly not in this day and age. From T.L. Davis at tldavis.substack.com:

I study the civil war/war of Northern aggression quite a bit, not as a scholar would, surely, but from all different sources and perspectives as it, and things like it, have developed over the centuries in almost every nation on earth. Initially, I studied it to write Shadow Soldier. I find the political conditions between British and Colonists to be very much like those between North and South.
To the degree that it exists here and now is not the same. While any given event might spur things along at a rapid pace, to make the comparison to our times, one has to go to the mid 1750s or the late 1840s. Then, all emotions were in place, anger, resentment, some injustices and killings, the sense that America was no longer British in sentiment, nor the South no longer Unionist in sentiment are the same, but it would be a decade or more before actual hostilities.
The North is being colonized by Islamists and the South is being colonized by criminal aliens and one might wonder whether the actual war to come is between Catholic/Christian versus Islamist states. In Texas, that division and antipathy is largely diffused, but might encounter consolidation as Islamic centers around Northern Texas rub up against the more Catholic/Christian centers further West and South.
The point being made is that due to decades long indoctrination in schools dating back to perhaps WWII and the horrific wars that took place in Europe brought into teaching a passivity and a belief, somehow, that if one side demurs, the other side will also demur when it is proved throughout all of history that the side that demurs is simply taken over and destroyed.
