When an audience completely disagrees with your position convincing them that their reasons for disagreeing are faulty before presenting your own position may be the best strategy.
Introduction: States the issue to be addressed and why it is important.
Body of Argument: Examines positions already proposed and refutes each one, showing why they are inadequate. Typically organized like this.
- Position 1
- Your refutation of position 1
- Position 2
- Your refutation of position 2
Alternatively, all positions might be examined first and then refuted second.
- Position 1
- Position 2
- Your refutation of position 1
- Your refutation of position 2
Conclusion/Position Statement: Once all other positions are shown to be inadequate, conclude with your position as the only logical choice.
