both, it's not either or it's about recognizing how the world has perpetually exploited blacks, and that now we all must stand up for them because we're all human, we don't chose our parents or how they raised us, but we can choose how to educate our selves on the matter of systemic racism and collectively unlearn the racist subtleties each of us have to better work collectively as a people moving forward into a future where block chain will empower us to develop new systems that work for us all and that can't be destroyed.
slavery is nothing new it always existed, black africans where never as explioited in numbers compared to other nations.
secondly the term "exploit" has a positive and a negative meaning, when africans where exploited people considered that "usage" not "exploitation" putting wild hunters and gatherers into organised plantation wasn't necessarily something negative, they where likely to die from snakes, animals etc.
race relations can't end as long as we have still a racist mob in the midst of the world.
