In the Papal Bull of Jan 1455, Pope Nicholas V commanded King Afonso V of Portugal and others to go into Africa

Here's the thing, until 1455, the color dichotomy that now shapes our world didn't exist.

It all began on the 8th of January 1455 when Europeans were given a religious obligation by Pope Nicholas V.

In the Papal Bull of Jan 1455, Pope Nicholas V commanded King Afonso V of Portugal and others to go into Africa and:

"Invade, search out, capture, vanquish and subdue all Saracens and pagans whatsoever and to reduce their persons to perpetual slavery and to apply and appropriate to themselves and successors their kingdoms, counties, principalities, dominions, possessions and goods and to convert them to your personal use and profit...to posses all movable and immovable treasures held by them (Africans) and to deny them their fortunes and ensure they remain defeated."

This was a religious command by the highest religious authority in Europe.

So to understand the genesis of the problem, you need to understand it was a religious command.

A command issued by the representative of "God" on earth.

Pope Nicholas died 2 months after he gave the order.

The colonialist didn't think they were doing anything wrong.

To them, they were obeying God's command.
