Discovering things is not what Christopher Columbus did.
You cannot discover something that is actively populated with it’s own systems in place.
What he did was rape, pillage and plunder. That’s really it. There were already people there utilizing the benefits of the land, so he couldn’t have possibly “discovered” them.
What he did, in fact, was give us the perfect example needed to coin a new term — “Columbusing“.
What he did was succeed as an imperialist colonizer who stumbled upon a shiny thing he really, really wanted, and he did whatever he could to make it his.
He’s a fucking fucker, is what he is.
