All societies are genocidal, but America is exceptional because of the art and technology it contributed to the genocide effort.
America is genocidal, sure, but so is every single other society in the history of civilization. America is exceptional because of the technology and the art it contributed to genocide, which is the goal of every civiliztion, remember. Pointing out the difference in scale of US atrocities just prevents us working together for greater justice.
Aside from that not being what a mistake is, others have noted that in fact most countries have shown no interest in doing what the US has done, as can be seen from many countries existing for hundreds of years without sanctioning chattel slavery.
I don't particularly remember making the claim that the US was unique in its use of chattel slavery, though your own source admits
While only 300,000 arrived in the U.S. directly, more came to the present-day U.S. via the intra-American slave trade
And the numbers here are skewed by the US being counted separately from Britain while Portuguese colonies count for Portugal, to say nothing of the fact that most African diaspora slaves in the 13 colonies/US were born there, over 10 million, far more than what Portugal has in your chart.
You're doing Holocaust-denial-level dogshit apologetics for your precious little white supremacy capital.
Even if we granted Portugal did more slavery, Portugal isn't the world hegemon doing more than any other nation to maintain imperialism for the past 80ish years.
Looks like you might take that up with the authors of the page I linked to. It's your inference, not mine. My position is there is nothing uniquely American about the behaviour.
You are such a fucking idiot, that's not what the page says. The page documents how many slaves were trafficked in the transatlantic slave trade based on the flag of the ship carrying them (which incidentally means the 13 colonies are counted under Britain). The vast, vast majority of slaves in the US were not brought there from Africa but born on US soil, as I already said. You are demonstrating not just your idiocy but your sniveling insincerity when you say "I didn't say anything like that" despite simultaneously arguing for that point, even after I explained that it was false and your source has no bearing on that fact.
