I don't know if you genuinely don't know about Jefferson, or not.

Thomas Jefferson unquestionably owned slaves, and he fathered five children with one of his slaves*. He made his own Bible by cutting out the parts he didn't like with scissors. So like all of them, he was full of his own crap.

*And he inherited her from his father in law, who was also her father. Meaning Sally Hemings was a half sister to Jefferson's late wife. Jefferson likely started sexual relations with her when she was 14, and also probably started when they were in Paris. Legally, Hemings was not a slave in Paris at the time.
