The history of slavery, according to social justice ideology

Among the myriads of tactics that the modern social justice ideology has come up with over the decades, historic revisionism is, rather naturally, one of them. Since in their view white people are a separate all-evil subhuman species that's only destructive, has never created or invented anything, and has always only stolen and oppressed everybody else, and all the other races are ascended superior angelic beings who have never done anything wrong, rather naturally history needs to be changed to reflect that fact of nature.

Of course they have not yet come up with or published one single Holy Book of revised history that lays out their new improved history (that paints all white people as rats and cockroaches, and all non-white people as perfect superior beings). However, over the years and decades their narrative has in increasing manners going into a particular direction.

If you were to believe what many of these social justice warriors are saying, slavery did not exist before white people invented it. On the contrary, all non-white societies and cultures were pretty much an utopia, peace-loving people in harmony with nature.

In their view ancient history was like one of those animated movies where forest creatures live in peace and harmony, and are one with nature, and then humans come with their machines and their pollution and destroy the ecosystem and habitat of the woodland creatures, and start killing the creatures and taking them as captive in cages.

But in this case it was the non-white people who were the peaceful nature-loving woodland creatures, living in peace and harmony, minding their own business, until the evil white people came and destroyed their lands and villages, and took them as slaves.

The social justice warriors (well, at least most of them) don't outright deny that, for example, black African people enslaved other black African people from other tribes. However, they argue that they did that only because they learned the practice from white people, and did so only to sell those slaves to white people. I'm not even kidding or exaggerating (there indeed are social justice warriors who are directly making this claim.) They are seriously claiming that slavery was invented by white people, it did not exist before white people invented it, and that other cultures started the practice only because they learned it from white people.

Of course in actual reality slavery has existed for pretty much as long as there have been significant populations of humans capable of warring with each other and taking enemies as captive. And it has happened during the entire history of humanity in pretty much all human societies, no matter where they lived, with very few exceptions (and those exceptions tend to be really small isolated tribes that usually were too weak to really go into grand-scale war and take prisoners of war).

It doesn't matter which part of the world you look at, which peoples you look at, there has been slavery among them, long, long before those peoples even knew that "white people" exist. Heck, longer than white people have existed period. You can go to the areas and peoples that nowadays live in China, India, Japan, all of Africa... you name it. Slavery has always existed, everywhere.

Heck, take the Aztecs, for example. The people who eventually became the Aztecs lived in complete isolation in Central America for millenia, before any of them had ever even seen a white person or knew that they existed. The Aztecs not only engaged in massive amounts of slavery, capturing tons and tons of slaves from enemy tribes, but moreover they likewise engaged in massive amounts of human sacrifices of those slaves. (According to their religious beliefs, several of their gods required massive amounts of sacrifices of slaves in particular. And that's when they weren't sacrificing women and children by literally ripping their hearts out of their chests.)

The one thing you'll never hear a social justice warrior acknowledge, however, is that it was white people who pretty much ended the practice of slavery worldwide. Or, principally, the British. It was the United Kingdom that forcefully stopped the trans-Atlantic slave trade from Africa to America, and elsewhere. The United Kingdom literally sent warships to blockade these slave transport ships, in order to completely end this inhumane practice.

Good luck trying to make social justice warriors acknowledge that fact, without any "buts" and weasel words. They cannot acknowledge this fact (at least not without any "buts") because they have been indoctrinated into believing it to be unthinkable and impossible.
