Reverse Middle Passage - Rwanda Buying Black People

In any discussion on slavery and reparation with the British, the British love to highlight that the slave trade was facilitated by Black Africans, capturing and selling other Black Africans to white slavers. I am neither going to support or deny that narrative because I do not know the circumstances surrounding their decision to take part. If it was done, did they do it out of greed or fear? A bunch of heavily armed white people turn up at your village and demanding you or the people in the other tribe, then the human survival instinct kicks in. However, the recent news that Rwanda will be paid to take refugees already in the UK, off British hands filled me with disappointment. If the British were right then Africans who use to sell other Africans to the British, are now buying Africans and middle easterners from the British. A kind of reverse middle passage. Denmark also has a deal with Rwanda to take refugees. So, Rwanda is trying to make a profit trading in human souls...
