only that earlier in his long life Franklin was ambivalent
he was a bit older when he became involved in emancipation efforts, working in established organizations, etc.
that’s all
Hamilton, it should be noted, was always against slavery because of the horror he saw in the Caribbean
Most of the slaves imported to the Western Hemisphere went to central America, South America and the Caribbean. Only 5-6& came to North America. The future was made in North America and England, as far as the end of slavery is concerned. Blaming the Founding Fathers for the collective evils of slavery, is wrong.
