Teaching daughters to be responsible for not getting sexually assaulted implicitly communicates that men are not responsible. It can easily be interpreted as victim-blaming.That view grows out of our current mental models. Those mental models are the crux of the problem. Protecting yourself from criminal intent in no way absolves the criminal of guilt.
We don't draw that conclusion about any other crime. We don't tell people that thieves are not guilty of a crime if you failed to lock your house. We still encourage people to lock up to protect themselves from robbers while not thinking this somehow makes it your fault if the house gets broken into.
If you run into a bear in the woods and you run from it, it will incite the bear's chase instinct and get you mauled. Teaching people best practices for how to reduce the odds of getting mauled if they run into a bear is not saying it is their fault. Refusing to teach them how to effectively handle it because girls shouldn't know such things means girls will either not go out into the world or they will routinely get mauled. Both of those outcomes are harmful to the lives of girls. Neither one gives girls full lives end par with the guys.
There will always be predators. You will never achieve a perfect world. Not arming women to cope effectively with that reality essentially dooms them to sooner or later get preyed upon.
It also actively teaches them to be prey. But that's a nuanced discussion you are probably not ready for and I am not super awake either, so not really up for anything that challenging.
