I have no problem with respecting NB Forrest's skill as a military man. Nevertheless, the founding of a fortune based on the selling of fellow humans speaks more to me of his human nature than public platitudes late in his life.
Maybe he did repent his sins, but unless he made recompense to every human he sold on the auction block, that repentance was sorely late and lacking.
The discussion isn't about his personal faults, but his leadership and ability as a strategist.
Lots of people made their fortunes on that peculiar institution, or benefitted from it - including many founding fathers.
I see no reason to color every discussion of Jefferson et al with bringing up slavery.
