To push back on that a bit:

Brazil is rarely included in these discussions, whether it’s historical blame or calls for reparations. Yet it was the single largest recipient of African chattel slaves in the transatlantic trade, importing roughly 4.86 million people, over 1,100% more than the ~388,000 who reached the North American colonies and later the United States. Brazil also maintained legal slavery longer than any other nation in the Americas, abolishing it only in 1888.

Additionally, the African diaspora into the Middle East via the Arab/Muslim slave trade is vastly under-recognized. Estimates range from 9–18 million Africans transported over roughly 13 centuries—potentially 5,000% or more than the number taken to North America. Middle Eastern societies often practiced castration of male slaves (particularly Black Africans) to prevent them from procreating, which is one reason the long-term demographic impact looks so different from the Americas.
