Stephen Baskerville describes no-fault or unilateral divorce based on no fault as a power grab by the parent that initiates the divorce and he also states that fathers have a constitutional right to shared control of their children and through political action they intend to establish parental authority for both parents and for the well-being of their children. Members of the fathers' rights movement state that a rebuttable presumption for shared parenting preserves a child's protection against unfit or violent parents.
