 Most feminists see the dual requirement of force and nonconsent as redundant at best and, at worst, as defining many rapes out of existence. Feminists differ, however, as to how rape laws should ideally be structured. Perhaps the most common view is that the force requirement should be eliminated, and rape defined simply as nonconsensual sex, with differing degrees of severity depending on whether and how much force and violence are employed (Estrich 1987). While some state statutes are now written this way, they often build physical force into the definition of non-consent; thus in practice they function very much like the dual requirement of force and non-consent (Anderson 2005a, 630).
