Noooo... i mean their behaviour prior to abuse, not after. The implication was made that 'victims of rape/abuse tend to have more abnormal sexual behavior than non-victims' within the context of banning sadism / masochism and to me that implies them as a causal, not caused aspect of rape and abuse.
Obviously rapists, abusers, etc themselves are wrong in the head, though. IMO - I'm not sure of clinical support - rape in particular is seen to be more about power and dominance than the actual sex aspect of the crime. So i can see rapists (or those inclined to it) getting a kick out of S&M, but i'm not sure you could classify that as being causal to the act of rape, or simply an interest which arises from existing mental defect.
I know about the potential psychological effects of rape, and the general theory that the abused with be inclined to become abusers.
