In the words of Thomas Jefferson over 240 years ago:
"It will probably be asked, "Why not retain and incorporate the blacks into
the state, and thus save the expense of supplying by importation of white settlers, the
vacancies they will leave?". Deep rooted prejudices entertained by the whites; ten thousand
recollections, by the blacks, of the injuries they have sustained; new provocations; the
real distinctions which nature has made; and many other circumstances, will divide us into
parties, and produce convulsions, which will probably never end but in the extermination of
the one or the other race."
-Thomas Jefferson
