An argument from Confederates in the Attic

"I like Auschwitz... It makes me wonder how human beings can possibly do that sort of thing to each other, and how you keep your spirit in that situation. Then I got to thinking about Salisbury's prison..."
Beth, a little girl in the Children of the Confederacy, argues that the concentration camps during the Civil War were too cruel. She claims that how they treated prisoners in the concentration camp and prison was way too cruel for human to do it. She is speaking this to the author but audiences can be any other Americans who did not know much about prison during the Civil War. She makes successful appeal by telling an example of condition at prison, how some prisoners killed themselves at Salisbury. She is using anologies when she compares the Jewish concentration camp with the prison in the Civil War and makes arguments based on facts and reason.
