I think his point is that there are risk factors associated with choices and it's valuable to be aware of them and attempt to mitigate the risks.
Obviously the fault doesn't lie with the victim, but since the world can be dangerous it's important to be aware of that reality when making choices. If certain actions increase your risk (walking alone at night, taking naked pictures etc.) then it's better to consider that when making a choice in order to avoid potentially becoming a victim.
You're only in control of yourself - while we can and should strive to make changes to our culture and the system, that doesn't mean individuals should be blind to how their own choices may contribute to increasing their risk of being victimized.
