Think of a person you feel is an effective rhetorician (this can be anyone someone famous, someone you know, etc) and discuss the following. 1) Who is she/he? What methods do they use (where do you encounter her/his rhetoric)? In what forum do they use rhetorical appeals (the classroom, the football field, church, etc)? 2) Why are they effective? 3) How has his/her/their contribution as a rhetorician actually influenced or affected your life? What can you deduce about their methods? Remember, you are obviously a "member" of this already persuaded audience were you always? 4) How might knowledge of this person and her/his methods help you produce an effective collaborative proposal that actually incites people to change?
An effective rhetorician. Let's see, I'm going to go ahead and assume rhetorician is some sort of jargon for a person who uses rhetoric and argues things effectively. I think I'm gonna go with Razmere. He's a guy here on dA and over on YouTube, now that I think about it I should of just used one of his videos for Blog #3, oh well no crying over spilled milk. Razmere often uses comedy in his arguments, but he can be serious and is at appropriate times too.
One of his things that I like to watch whenever I feel like things are getting tough, convoluted, or otherwise overwhelming is his Believe! Rant,
[link] It just makes me think, Alright! I can do this. He uses nice dramatic music making it clear that this is going to be a serious thing that he's talking about. And he addresses the issue, making a nice reference to an anime at one point which makes it even more motivating since in the anime the kid it gets said to then goes on to take out a giant mech. It's one of those David and Goliath things. You see this scrawny little guy go and do something amazing and you think. Hey, if he can do it so can I!
Razmere's target audience is made up of young adults who watch like to watch anime. His references, word choice, tone, music, and overall presentation is highly entertaining, grabs your attention, and makes it hard not to get excited about what he's talking about. Assuming you were targeting a similar audience his methods could help you persuade them, although since his methods seem mostly internet based it might require some tweaking to work on groups in different settings.
