The correct answer is A) Taney fails to provide any actual evidence for his statements that African Americans were universally considered inferior.
Indeed, during the American Revolution, there were black spies and soldiers who fought in the American side and were emancipated as recompense. 9000 blacks were part of the Continental army and actually fought longer than many white soldiers. There were several free blacks in northern states and several of the Founding Fathers loathed slavery, even Jefferson, who owned slaves disliked the institution.
Therefore, Justice Taney’s reasoning is based on a false premise since the views of white Americans on blacks during the Revolutionary war were highly divided and divergent.
