In "Narrative of the life of Frederick Douglass", how does Frederick Douglass's writing make his audience feel about slavery?

Douglass
uses emotional appeal to make readers
feel that slavery is a horrible institution that
dehumanizes everyone
associated with it. He does this by describing in graphic detail the
cruelty
of the masters. For example, he begins with the traumatic beating of his young aunt
by
their master, who tied her arms above her head from a hook in the kitchen
ceiling, stripped off
her clothing to the waist, and beat her bloody while
forcing the other slaves to watch. This was
traumatic to the young Frederick.

Douglass also refutes white people at the
time who
believed that slaves were happy. Two commonjustifications for slavery were
the
following. First, people would hear slaves singing and think that their
songs signaled happiness
and contentment: Douglass is at pains to explain the
songs meant sorrow. Second, slaves, when
asked by whites, would often say
they were happy: Douglass shows this is from fear of
retaliation if they
answered honestly.

Another justification for slavery was

that the slave owners were Christian: Douglass illustrates that a "conversion

experience" simply made masters crueler because they believed the Bible justified
slavery
and because it taught them that slaves must obey their
masters.

These are
just a few examples of the many ways
Douglass shows slavery to be a horrible institution. Nobody
would be likely
to come away from the book thinking there is any humanity in slavery or that

slaves in any way had a good life.
