One of the problems with leftists: if what they're pushing is bullshit, they don't care

as long as they can keep pushing the bullshit.  Such as Hannah-Jones does with her '1619 Project', and idiots help her along.  Such as by pushing this clown as a emancipator.
Indeed, when Dunmore fled the capital, he carried away a sizable staff of "servants" from the palace grounds and relocated them to Porto Bello, his sprawling plantation a few miles up the river. Yes, the 1619 Project's designated agent of "emancipation" for the British crown was an enslaver himself. Dunmore encamped on a succession of warships anchored in the nearby York River, never to return to the building where Holton erroneously situated the decree. He occasionally took a barge over to the plantation house at Porto Bello to enjoy fine dining with his officers, served by his relocated slaves. But that ended as patriot militias gained control of the peninsula on which the property sat, and Dunmore withdrew to Norfolk. By November 7, 1775—the date of the order—he had long lost any semblance of control over the colony. The decree anticipated an unsuccessful campaign to regain a foothold in the colony. In retrospect, it was a desperate move to restore himself to power by inducing a slave revolt amid the already-unfolding revolution, rather than any true attempt to affect "emancipation" at large.

And yes, there's a lot more.
