One can find out all of the "White man's" intentions by just reading Columbus's diary of his first voyage to the New World:
" "Many of the men I have seen have scars on their bodies, and when I made signs to them to find out how this happened, they indicated that people from other nearby islands come to San Salvador to capture them; they defend themselves the best they can. I believe that people from the mainland come here to take them as slaves. They ought to make good and skilled servants, for they repeat very quickly whatever we say to them. I think they can very easily be made Christians, for they seem to have no religion. If it pleases our Lord, I will take six of them to Your Highnesses when I depart, in order that they may learn our language... I could conquer the whole of them with 50 men, and govern them as I pleased."
The other revealing aspect, of course, of this passage is that slavery was never just White men enslaving Black -- but then most of us knew this already. But Columbus's first voyage was in 1492, and the slave trade from Africa to the New World began barely ten years later.
There was much bloodshed, from both sides, but that does not lessen the guilt of those first colonists who so quickly brought a new and deadlier form of war, and disease, and the most vile form of trade to the Americas.
