Not promoting anything of the sort. These are factual observations of history, any student of history feel free to chime in so we can focus on facts over feelings.
>The African peoples are more than the slave trade, more than colonialism.
I agree African history is much more than slavery, but the European invention/export of racist theories/science and the dehumanization of Africans started during the same period (The Renaissance, ~15th-17th century continuing into the 21st century) Africans were enslaved and robbed. This period cannot be ignored in any discussions of the history of racism.

"Scientific racism was common during the period from 1600s to the end of World War II. Since the second half of the 20th century, scientific racism has been criticized as obsolete and discredited, yet historically has persistently been used to support or validate racist world-views, based upon belief in the existence and significance of racial categories and a hierarchy of superior and inferior races."
