“If what you say is true, if the Constitution is indeed pro-slavery, then there is no such thing as American Exceptionalism.”

Exceptionalism is not the same as abolition. The two are different.

America has long been recognized as exceptional, even during the period before the 13th amendment.

The position you have taken is radically leftist. The problem is, this comes full circle. By agreeing with the New York Times 1619 Project that the Constitution is pro-slavery, you are also agreeing with everything down stream. You can't separate them as if there's a magical line in the sand.

"America has long been recognized as exceptional"

America has long been without the 1619 Project too. You appear to be wanting to have it both ways. You want to carry the banner of the New York Times high and proud, and you want to carry the banner of years of old-time recognition as well. But you're not realizing the gross contradiction of the two.
