She could have expressed her intent more clearly, but I agree with what I think she was saying:
If I leave my Lamborghini unattended with the door unlocked, the key in the ignition, and gold coins sitting on the dashboard, and someone comes along to steal it all, he's still guilty of theft. That said, I still could have taken reasonable precautions to at least reduce that risk.
I will say this though. A person who has never been sexually abused before could reasonably trust people more. In fact, even a person who has been sexually abused before but in different circumstances might still trust that he has nothing to worry about in the new circumstances. People do not just instinctively know where danger lies. That requires education.
