I'm dubbing your best bet the "speaker switcheroo." This works best with predictable, time-honored objections that have no basis in reality. Things like "Everyone who uses Facebook is going to lose their job someday over some picture they posted" or "women can't handle the stress of these senior-most jobs." The objections you can counter with the speaker switcheroo are sweeping and erroneous, but also familiar to your listeners, and you can upend them simply by replacing a word to show how off-base those objections are today--and always have been.
Here are two examples that will get you thinking about how you can use this rhetorical trick of turning your opponent's arguments to your advantage:
- Nellie McClung's "Should Men Vote?" speech, featured in our Famous Speech Friday series, is a classic example of this technique. The suffragette took common objections to giving Canadian women the right to vote, swapped the word "women" for "men," then put a parody hearing together in which the question of whether men should vote was debated--using her critics' own objections. "Man is made for something higher and better than voting" is just one example.
- A more recent example can be found on Twitter in Pencilchat, in which education pros are combating tired objections to technology in the classroom by swapping the words "computer" or "Internet" for an older, revered technology, the pencil. Using the hashtag #pencilchat, teachers are posting objections to new technology with the pencil twist, yielding funny results like "I don't know why we have to let them have pencils. All they are going to do is cheat" and "Too many teachers need additional training to integrate pencils into the learning environment."
