Extended abstract frameworks separates conflicts and preference be-tween arguments. These elements are combined to induce argument defeat rela-tions. A proper defeat is consequence of preferring an argument in a conflictingpair, while blocking defeat is consequence of incomparable or equivalent-in-forceconflicting arguments. As arguments interact with different strengths, the quality ofseveral argument extensions may be measured in a particular semantics. In this pa-per we analyze the strength of defenses in extended argumentation frameworks, un-deradmissibilitysemantics.Amoreflexibleformofacceptabilityisdefinedleadingto a credulous position of acceptance
