Slavery was always a part of life until Christianity came in and people started caring for other races. Finally after hundreds of years it was abolished in America. A whole war was fought about it. In the end the life you get is the one your parents give you. It's up to us to make it better for the next generation when we make our own kids.
Slavery still exists to make batteries for electric cars, cheap clothes, and more, also for sex trafficking. And no one seems to care. We all benefit from slavery right now and we need to realize it and stop supporting it with our dollars because we the people are going to pay for it one day just like your post above. How many countries have we f'd up the last 20 years with bush and Obamas endless wars in the middle east. Now trump is indicted because he took documents that revealed a secret cia level plan to invade Iran.
We are pissing off the world and they all have the same mentality against us that you do against all white people from your post above. Some white people had slaves but a lot were immigrants that ended up in slave-adjacent scenarios so it's just dangerous and inaccurate to divide two skin colors by this metric. We weren't all decended from slave owners, and we're all currently getting owned by our government so maybe lets move past the 1800s.
