#blacklivesmatter racism is a human problem

Nah - it's everyone's problem. You can't make it one groups problem because then the impetus is on them to fix it. White supremacists aren't going to end white supremacy on their own - everyone has to join together otherwise nothing is going to happen.

You also have the issue of one groups solution probably not being accepted as the end by any other group. For example the British slave-trade past; if we leave it up to the rich people whose inherited wealth comes from the British slave trade, they will probably think job done on fixing past wrongs when they move a few token statues into a museum somewhere & put up a plaque saying they were a few bad apples of the time. When that's probably not going to be job done for anyone else.
