Chapter 13 opens with quotes by Frederick Douglas on the horrors of slavery. I have read that Douglas wrote three autobiographies. The Douglas autobiography I read discusses the relationship between the slave owner's Christianity and their propensity to whip slaves, sometimes while even quoting the Bible. After describing several chilling examples, he explicitly says that given a choice between a devout or nondevout master he would choose the nondevout. My point is that your essay is missing some good Douglas quotes.
