forgetting the fact that every ethnicity has been in slavery at some point in their historyAnd he forgets that the vast majority of people of European ancestry NEVER OWNED SLAVES.
Or that it was the people of European ancestry who were the first to figure out that owning other human beings was immoral and were the first people on Earth to make it first uncommon and then illegal. Here in the United States they expended a whole lot of their blood and treasure doing that.
And that free blacks in the USA owned slaves too just as did their African ancestors.
Nobody is commending or justifying or sugar coating slavery, but as Walter Williams PhD once said, had not some slave traders dragged his ancestors over here to America who did finally reject slavery and afforded unalienable rights to all its citizens, he would not be a respected professor of Economics at George Mason University but would probably be dirt poor and die young in some Ivory Coast slum and could very well have descended from slaves there as well as here.
To condemn one race of people with slavery in its past purely on the basis of its skin color and not condemn all peoples of all colors who have engaged in slavery--which would include just about everybody's ancestors--is just not thinking clearly I think.
