Answer:
The correct answer is It establishes Douglass as a moral man.
Step-by-step explanation:
Douglass mentions God's curse on Ham and how, using the Bible, white slave owners used these writings, hypocritically, to continue capturing slaves with the excuse that they were their descendants.
This is supported by the following quote: “Whether this prophecy is ever fulfilled or not, it is nevertheless plain that a very different-looking class of people are springing up at the south, and are now held in slavery, from those originally brought to this country from Africa; and if their increase do no other good, it will do away the force of the argument, that God cursed Ham, and therefore American slavery is right. If the linear descendants of Ham are alone to be scripturally enslaved, it is certain that slavery at the south must soon become unscriptural; for thousands are ushered into the world, annually, who, like myself, owe their existence to white fathers, and those fathers most frequently their own masters. ”
