I’m sorry I had to give you that F on your rhetorical analysis. It’s a difficult thing, ripping apart someone else’s words in the search for meaning. You had a hard time with Martin Luther King’s “Dream” speech, and now Frederick Douglass has you stumped. But free speech doesn’t come freely; it takes practice and thought. Neither man hit on their exact wording accidentally, and neither should you. Dry your eyes, grab a thesaurus, and try again.
