The 1619 Project ignored the most important development in Virginia in 1619—the first meeting of the House of Burgesses, the beginnings of self-government in the English colonies. That is what led to the later emergence of the United States as a republic (which included some states which regrettably had slavery and other states which did not have it, or in which it was insignificant economically).
Now c’mon, when you have an agenda you stick to it. Facts be damned.
