1. Reinforce victory (on, say, abortion, where the culture shifted a long way from Fast Times at Ridgemont High to Juno)
2. Know the other side's arguments better than they do.
3. Always challenge -- never back down -- except in the face of superior reason (my conduct in the academy since I entered college at 15).
4. When accused of something, your first impulse should be to admit it.
5. Study the abuse of power not just to protest abuse but to learn how to gain and keep power.
