Answer :
The only way Douglass can reconcile speaking at a celebration of American freedom is to speak about American slavery, so that's what he does. He points out all the ways in which it is seriously messed up for white Americans—even abolitionists—to celebrate their own freedom while people are held in bondage. He points out how hypocritical it is to celebrate the nation's freedom while the nation is actively false to those ideals.
Answer:
A. He wants to convince his audience that it is wrong to celebrate independence while denying freedom to slaves.
Explanation:
It makes the most sense because in his essay, he's been talking about slaves and he's convincing his audience that Amerricans should be ashamed to celebrate the 4th of July as long as they allow slavery to exist.
I don't know if it's right but I hope it helps!
