What am I to argue... -- This section of Douglass' speech reiterates the "any man" voice, illustrating the ignorance of the black man as animal argument. Douglass claims it is not worth his time or energy to debate or discredit this argument because a thinking, rational person knows this to be untrue. Douglass takes on this voice here and in several other passages to appeal to the common sense in all people and the ego that tells them they are logical and intelligent.
