From the article:
"And how many of these 10.7 million Africans were shipped directly to North America? Only about 388,000. That’s right: a tiny percentage."
~3.7%
Slavery of course is an abomination, and so that was 388,000 too many (along with there descendants) even where I live in the rural Southern United State only a small fraction of the citizens owned slaves.
I have some separate thoughts on Nationalism but wanted to let them properly develop.
Tangentially and bizarrely one of the largest slave owners in North Carolina was himself a former slave - https://en.m.wikipedia.org/wiki/John_Carruthers_Stanly
