The debate worlds head is exploding at the proposition of Affirmative debaters having to demonstrate that repeated domestic abuse meets the multiple conditions for qualification as self-defense. For deadly force to be justified as self-defense, the conventional logic is that certain requirements must be met, namely: the threat must be imminent, and deadly force (as opposed to less deadly alternatives) must be necessary for someone to prevent serious harm from being inflicted. Proportionality may also be considered a requirement insofar as it wouldnt be acceptable to use deadly force to stop a minor affront or injury.
In the most technical sense, a 1NC that requires the 1AC to demonstrate how repeated domestic abuse is consistent with these requirements is indeed holding the AC to multiple necessary but insufficient burdens. This should say more about our impoverished burdens theory than it does the abusiveness of the NC strategy.
After all, in many instances, the 1AC is advancing self-defense as a justification.
