According to Professor Marshall C. Eakin during his Great Courses series Americas in the Revolutionary Age, the US, between the time of the Colonies to the 13th Amendment, would only have 8% of the total African slave population That just means the population of enslaved was horrifying in total, not that we only held 8%. It's way too early for math- if the 4 million enslaved human beings in the United States in 1860 composed 8% of the world's enslaved population it means the whole was staggering, not that the United States was somehow more compassionate. It's also a kinda smoke and mirrors, ' they did it too ' excusatory perspective. Bet if anyone asked a single enslaved they'd hold the opinion slavery was sure not exagerated anywhere at all. Why this topic arouses the kind of vitriolic, accusatory sentiments it does in defense of what genuinely was the barbaric practice whereby anyone thought it possible to own a human is beyond me.
