The demands seem reasonable.
Jefferson, like most human beings did both good and bad throughout his life. On the good side, he far, far outclasses Confederate generals (and most of us today, too). Jefferson rebelled against a bad government that refused to give his fellow Americans representation.
The generals had their 'greatest' personal moments slaughtering their fellow countrymen and revolting against their own working government so that they could continue to refuse representation (and be free to inflict many other great horrors) on a selection of their fellow Americans.
(I also think that Jefferson's relationship with his dead wife's younger sister is near never publicly addressed as being as complicated as it clearly was.)
Huh. Never knew he had that relationship.
He means Sally Hemings, who was the illegitimate daughter of Betty Hemings and John Wayles (Martha Jefferson's father).
