Challenge an opponent's argument by questioning his motives. Many readers will let you sidestep an issue with this maneuver. Of course our opponent wants an end to child labor, the secret police, and the gulag for political dissidents. He just wants people to think he s a nice guy. Don't miss an opportunity to wrap your own position in glittering generalities.
Readers like to feel inspired by grand statements.
Our Great Leader has long been a selfless champion of the great freedom-loving people of this great nation. Use emotionally-loaded language. A little name-calling goes a long way, too. You can make it seem like an attack on the entire argument. Our opponent believes that people imprisoned for their political beliefs should be freed.
