So, in reality, the founders prior, during, and after the revolution were not a monolith and it was a complicated issue.

There were founders who had abolitionist sympathies and goals, but political compromises had to be made, because a number of states still relied on slavery to maintain their economy, to ensure there was any union to be had at all.

For example, Jefferson had abolitionist sympathies written into his original draft of the Declaration of Independence, admonishing the crown for its role in enslaving and transporting African slaves to the Americas, but that segment was edited out in committee. He expressed some unkind words about the practice and even advocated for some possible solutions, granted he failed to emancipate almost all of his own slaves.

We already know some of the colonies were pro-slavery and others worked on legislation for gradual emancipation of the slaves.
