In class: thinking rhetorically

I found the definition of "rhetorical" to be a bit challenging. The book defines a rhetorical analysis as a close reading of a text to find how and whether it works to persuade. The rest of the chapter goes into deep discussion on the variety of different text that can be used to persuade while emcompasing the previously discussed pathos, ethos, and logos. Which was all pretty self explanatory. The part that really confused me a little bit was when it stated, "Don't be surprised when your rhetorical analysis itself becomes an argument. Tha'ts what it should be." A few pages later, chapter five was very helpful by giving a quite to writing a rhetorical analysis. As far as unit two goes, i am very comfortable with the first two steps, which is choosing a topic and find different sources for the topic. I am thinking i would either like to do Obama's decesion to close gitmo, which falls into my major category, or the decision of the episcopal church to condone a homosexual bishop and the decision of some of the diocese including my own, to leave the episcopal church and rejoin the Anglican communion because of it. I know i will be able to find plenty of information on this, im just a little confused on how to put it all together with my claim and proposal an how to organize it.
