Interesting, sad, and no surprise. From the linked article:

"Role in the History of Racist Ideas

In the 21st century, the work of Zurara has been re-examined for its foundational role in the development of modern racist ideology. Historian Ibram X. Kendi, in his 2016 book Stamped from the Beginning, argues that Zurara was the world's first racist because his chronicle was the first to articulate a comprehensive defense of the African slave trade based on the concept of Black inferiority.[12] Kendi posits that Zurara's writing was not the cause of the Portuguese slave trade but rather a product of it; Prince Henry's economic and political self-interest in the trade of enslaved Africans came first. Zurara was then tasked with creating a narrative to justify these policies.[13] According to this view, Zurara's chronicle established a powerful and enduring justification for racism by portraying enslaved Africans as savages who were being civilized and saved through their enslavement, thereby creating racist ideas to rationalize pre-existing racist policies.[14]"

I have nothing to say.
