No, no, no, no, no.
To quote an old soc.history.what-if post of mine:
***
...southern congressmen in the early 1790's--well before the expansion of
the Cotton Kingdeom--seemed as belligerent on the subject of slavery as
their counterparts of decades later. Consider the following remarks by
Congressman Jackson of Georgia in 1790 (before the cotton gin was even
invented) in response to some antislavery petitions:
"[T]he people of the Southern states will resist one tyranny as soon as
another. The other parts of the Continent may bear them down by force of
arms, but they will never suffer themselves to be divested of their
property without a struggle. The gentleman says, if he was a Federal
Judge, he does not know to what length he would go in emancipating these
people; but I would believe his judgment would be of short duration in
Georgia, perhaps even the existence of such a judge might be in danger."

Likewise, Federalist Congressman William Smith of South Carolina on March
17, 1790 made a speech attacking federal interference which "developed
every argument for slavery as a positive good which Calhoun would bring
forward half a century later."
