"I don't think we can imagine what slavery has done to the people here, it goes very deep, these things take a very long time long, even the opposition to colonialism has traces of it. Here it was quite late, 1830, but a little further west, slavery lasted 3 to 4 centuries, 40 to 60 million people are estimated, were moved from here, to America, that's no small thing, you would say that is an African holocaust."
