The Truth is not known.
The Truth cannot be known.
It makes no sense for anyone to profit from this, since it is an unknown. Now, ask yourself: are fans of Thomas Jefferson talking about Sally Hammings all the time? Are they saying Jefferson was a GOD! Why? Because he never fathered a child with this woman! Isn't that great?!
Wouldn't that be a silly claim? In no way can this alleged incident be used to boost Jefferson's reputation. As why should it? There's no proof, so fans of Jefferson have no reason to say much of anything on the topic.
BUT ... people who want to claim "everybody does it" have a real reason to smear him with an unsubstantiated "fact". Oh, sure, we don't know for sure, ... but, you know, everybody does it ... and one of the Jefferson men did it ... and, you know, it could have been Tom ... so, that's almost like proving that he was a hound-dog, right? So, I guess we can ignore all the verified sex scandals too ... because, you know ... even Thomas Jefferson did it.
In short: this is useful as a smear on a great American. The story can serve no other purpose. We don't have to declare Thomas Jefferson a saint, but we should say that this is an unfounded, unsubstantiated smear job. It has no use as anything else.
I don't see that.
At the time this may have occurred, Sally Hemmings was Thomas Jeffersons Property.
Anything he may or may not have done was neither illegal nor immoral in that context.
That it may be illegal or immoral today is irrelevant.
It did not happen today.
Therefore there can be no smear.
