I don't think that flies, because the point of her post was to identify a sexual assailant. She said she was the victim of an assault by another person, an issue of injustice which is a social and cultural question, and you said "Yes, but everyone is responsible for their own personal safety." This isn't about personal safety, it's about social justice, and yes, those are two very different things. So why are you trying to change the subject? The reasonable conclusion is that you're trying to weaken her claim to justice, which implies that you think we focus too much on justice, using social resources to protect women and they need to look out for themselves more.
