There was still a slave trade in North and South America prior to the Europeans coming, it was just their own people being enslaved rather than an importation of people from Africa. South and Central American empires were not all sunshine and rainbows; although North America did not have a standing civilization as far as I know, the tribes that did exist enslaved and killed each other constantly. People are shitty regardless of the continent they are born on.

Amongst some west coast tribes, a quarter of the population were slaves. Pre-colombian slavery was widespread, and could be war prizes, traded goods or a form of taxation.

Later, many tribes engaged in the Atlantic slave trade.

That really isn't what I was arguing but if you want to change the discussion then I'm open to it.

Really? Cuz the word on the street is that your mom fuels imperialism worldwide and invents and perpetuates the trans Atlantic slave trade.
