Unfortunately, the Maria Goretti narrative never said she was martyred for resisting rape--full stop. It made the situation sexual, and implied that Maria was good with God because she preserved her own chastity, not because she fought off a rapist. In other words, a girl or woman who allowed herself to be raped wouldn't likely be good with her family or God. This was basically the trickle down from this story. 

There is the strong possibility that this was fully intentional. At Maria's canonization Pius XII contrasted the "the unhealthy marshes and filth of the world" (read: sex outside marriage) with the "solemn duty" to be on guard against said dangers and the mother who "educated" Maria to this very martyrdom--and he used that word. 

Job well done, mother?  

It's so twisted I can't even wrap my head around it. And she is the patron saint of rape victims?
