I 400% agree we have to reflect on our past and unravel what has lead from then to today.
However there is another side to this. Unless you are a descendant of nobility or the royal family you are just as much of a pawn of the system as anyone? I will give you an example, I can trace my ancestors back to poverty and squaller in Britain during the height of the global slave trade, probably living off boiled potatoes, they like the vast majority of white Britain were a product of the system, if you looked into the numbers it would be a small concentration of Britain that actually have a hand in it, even less a number who authorised it.
That is not me writing history or trying to glaze over it, but a whole race is not individually accountable for this part of history anymore than the Italians are for the death of Jesus or all Germans are for the Holocaust.
The point I am trying to make is if we keep looking back we won't look forward, if we keep looking back at the international slave trade there will never be an end to the anger as it will always evoke angry emotions.
Your point "They hold the blame, they will forever" yes there will be blame to attach but the point forever lends itself to their never being an end, never enough apologies, never enough soothing and holding people who want to move forward, who are not racist who want an integrated society accountable for actions they had no control over.
We are all products of a past, we are all here in this generation as part of a path we had no control over, its what we do now that makes a difference.
