What is Defense in debate?
debate term
Responses that weaken an opponent’s argument without helping your side.
Defense includes takeouts and mitigation: their study is outdated, their link is missing a step, their impact is exaggerated. You need defense because it shrinks what you have to outweigh, but it can’t win a round alone. A judge fully persuaded by your defense still has no reason to vote for you. The strategic skill is getting the ratio right, with enough defense to contain their offense and enough work on your own offense that you have something left to weigh.
