I'm not sure how you think your ancestors experience in any way relates to slavery in the USA, the legacies of it which include Jim Crow and the fight for civil rights. You thought because slavery was over black's weren't hunted and killed with their killers going free? Do you think it was ok to form USA PD departments using KKK members? You thought that was a good idea?
Do you even know what the US justice system does and why for the same crime blacks get the 3 years while whites go home if they don't 6 months? Would you believe me if I told you a white judge refused to convict a white adult for using an object to sodomise a disabled black child that it wasn't sexual assault or even sexual in nature and sent him home?
Speaking of slavery and the legacies, do you know why confederate statues were erected? Do you know why it was a big deal to FINALLY remove them just the other day? Are there Nazi statues all over Germany? Then you'd wonder why they were all over the southern part of the USA right?
There is a lot to say on this subject that you clearly don't understand. You'll need to get the education outside of TERB. Any time you're ready for it, just say so. Every group's experience in the USA will be different Blacks and Native Americans were the two who here heavily targetted and everything they built was destroyed.
As for what happened hundreds years ago not mattering now, you should go tell that to Haiti. LOL. Enslaved. Fight for freedom. Owe your slave masters because you won and kicked them out. Debt finally paid off in 1947. Poor as fuck now. Piece of shit leaders (probably beholden to France) who steal from the people doesn't help, but still...
