The problem with that is it negates perception of the age. IOW, was George Washington less moral than Richard Nixon? James Madison less moral than Rod Blagojevich, Dan Rostenkowski? Thomas Jefferson less moral than Jerry Madoff?
Perception of the age? Thomas Paine was man of Jefferson's age & thought .slavery was deplorable & had more enlightened/truthful things to say about Africa than many Whites today(READ Paine's view of Africa/Africans)
John Adams & many others thought it was abhorrent as well & never engaged in it.
The Jefferson's & Washington's' were 'men of their times' is complete bull crap.
