And it's not just their nine year olds who think that way.
Thomas Jefferson warned us that, while the African slaves would need
to be freed, that once emancipation had occurred they would need their
own country separate from ours if we expected to be equally free.
"Nothing is more certainly written in the book of fate than that
these people [blacks] are to be free. Nor is it less certain that the
two races, equally free, cannot live in the same government. Nature,
habit, opinion has drawn indelible lines of distinction between them."
--Thomas Jefferson: Autobiography, 1821. ME 1:72
