Problem
Through analyzing their argument(s), evidence, word choice, metaphors and/or writing style, you will make a case for the credibility or lack thereof in terms of the case they make. There is a difference here between whether you think that their argument is persuasive or not, AND whether the evidence and claims used to support the argument are ones that are credible. Some of this will require you to research and find out whether or not the studies cited support what the person argues or are the studies taken out of context (or are quotes taken out of context). How might the writing work to favour the author's position against the truth, reality or legitimacy of those this person opposes?
Through your rhetorical analysis essay, identify the key factors that make it persuasive, or not, with its intended audience. This involves identifying particular keywords, metaphors (and related figures of speech: e.g. metonymy, synecdoche), means of persuasion (ethos, pathos, logos), style, invention, arrangement (disposition) and/or structure.
