According to Douglas, what did the founding fathers do about slavery?

Answer: they did nothing they didn't want to be part of it

Explanation:

The founding fathers had slaves themselves, they just didn't want to be involved and preferred for a future president to deal with.

Although many of the Founding Fathers acknowledged that slavery violated the core American Revolutionary ideal of liberty, their simultaneous commitment to private property rights, principles of limited government, and intersectional harmony prevented them from making a bold move against slavery.
