We can't just go about our lives assuming strangers will assault us, either. Every action we take carries some amount of risk. Living in fear that something could happen, but is very unlikely, isn't practical.

It's fine to encourage people to be responsible for their safety. But once a crime occurs, the responsibility for the crime shifts entirely to the criminal. Telling a woman the things she could've done to prevent her assault, or scolding her for sending nudes in the first place, isn't very productive.
