Thomas Jefferson was a lifelong hypocrite and slave owner.

It was absurd of Thomas Jefferson to assert: "the guarantee to every one of a free exercise of his industry and the fruits acquired by it" and then deprive both African Americans and Native American Indians the same right.
He should have demonstrated his respect for liberty by releasing all of his slaves from bondage and should have demanded all other slave owners do the same.
He should have become an abolitionist as soon as he wrote the Declaration of Independence in 1776.
At least Benjamin Franklin had the courage and wisdom to become an abolitionist while he lived.
