When I want to hear or give a persuasive speech, I favor some specific topics. One is politics. There is always a lot going on and changing in this subject, so every time somebody gives a speech about it, it will be different. Also, product comparisons are interesting. Everybody has different oppinions on which of two or more similar products is the best. Finally, restaurant comparisons are great, too. It's always interesting to hear why somebody likes one ice cream parlor better than another. Obviously, there are several extremely interesting topics for persuasion.
