I’m going to attempt to strip away the anti-leftist polemic and distill the actual tactics that Shapiro espouses:
Rule #1: Walk Toward the Fire
Be willing to take criticism head on and do not allow it to deter you.
Rule #2: Hit First
Be prepared, know your opponents weakness, and attack it immediately.
Rule #3: Frame Your Opponent
If your opponent attacks your character, don’t try to defend yourself. Instead, attack them on their tactics. If you know they will attack your character, attack them preemptively.
Rule #4: Frame the Debate
Choose the question for debate, rather than accepting your opponents framing of the issue. Use accepted standards to force them to accept your framing or look unreasonable.
Rule #5: Spot Inconsistencies in Your Opponent’s Arguments
When your opponent takes a position that is more reasonable than the one that they actually hold, look for inconsistencies and use them force your opponent to admit their actual position.
Rule #6: Force Your Opponent to Answer Questions
This tactic is primarily to put your opponent on the defensive.
Rule #7: Don’t Get Distracted
If your opponent makes an irrelevant counter argument, don’t let them divert you from your question.
Rule #8: You Don’t Have To Defend People on Your Side
Don’t allow attacks on other people on your side of an issue to divert you. “Don’t follow people. Follow principle.”
Rule #9: If You Don’t Know Something, Admit It
Shapiro suggests that you simply state, “I didn’t know that, but I’ll be happy to research and get back to you.” Don’t bring up topics you aren’t familiar with.
Rule #10: Let The Other Side Have Meaningless Victories
Agree on things that haven’t yet been defined when there is a definition that fits your argument. Agree on generalities that are so broad that they don’t hurt your argument.
Rule #11: Body Language Matters
“Whomever looks angriest in debate loses.”
