I don't think anyone is arguing the slave trade never happened. Just that it's overblown and in no way explains the existence of the 100+ million black people in the Americas today.
There is tons of evidence that supports the argument that there was a significant black prescene in the Americas BEFORE Columbus ever set foot in Haiti.
Most "black people" in the Americas are not descended from slaves from Africa. Rather we are descended from native black populations that are the first humans to set foot on the American continent.
I'd disagree.
And I think it's the shame that some of us carry for having been enslaved that drives us to illogical conclusions like this. I am not ashamed of it, rather puzzled and amazed that so many or ANY of us were able to endure and survive such trauma.
I've read some of the same books that you are alluding to, obviously sea faring Africans arrived on multiple continents centuries or millenniums before "europe" existed, but you are reaching.
There are too many distinct cultural markers between Western Hemisphere Blacks and specific West African ethnic groups for anybody to say that the majority of us are NOT the children of the enslaved people.
Again, I'm not inside your head, but from where I sit only shame would make a person see it other than how it obviously is.
