it makes me think of this quote from The Fall

""Men always think in terms of fight or flight," said Stella. "In fact, the most common instinct in the face of this kind of threat is to freeze. If she didn't fight, if she didn't scream, if she was silent and numb, it's because she was petrified.

"In that state of fear she might well have been compliant. She might well have submitted. But that does not mean she consented."

Whether you said no loudly or forcefully enough has no bearing on what someone else did to you, the responsibility does not lie with you saying no in the perfect way, you could not have prevented this by saying the perfect thing and to believe you could is just gross.
