Of course, there is the historical heritage of the exploitation black people suffered by white people, and this need to be acknowledged, taken into consideration and, in some way, repaid.
With special intensity in certain places but almost everywhere, black and white does matter still a lot.
But my point was that once ‘repaid’ the crimes committed in the past (and the present) by white people against black people and once enforced by law and culture a substantial equality of rights and opportunities, racism will not disappear, it will remain and transform. Because racism, or the fear for the different, is connaturated with the human being.
