I think it's extremely relevant that I wouldn't want to talk about this woman's actions in a way that would make her feel stupid. Without shaming her, I would hope to make her feel there was a need to change and a way to change. Perhaps having those conversations would discourage women from coming forward - but perhaps it might discourage other women from acting so foolishly. Also, if I were in conversation with her, while I would not want to diminish the wrong that has been done to her,I would want to tactfully point out that she walked straight into it when she put that damn blindfold on.
Pointing this out does not mean I think the offender is less guilty. However, I do think there is a ridiculous narrative going on here, which is that I can leave my personal safety entirely up to the judicial system to take care of because if something happens to me, it has to be someone else's fault and no one can suggest that my behaviour needs to change. This is a nuanced point. It is the predator's fault, but there is also a sense in which, aside from his crime, she was a fool. And there needs to be a way to talk about that. Mumsnet tends to be a place where conceptual debates are frank and fast moving; there isn't always time to pussyfoot around and say 'I would like to think this person might need to - ahem - think twice next time they put a blindfold on...'. Actually, you would have had a problem with that too as your primary issue wasn't with the use of the word 'stupid'.
When all is said and done, I do think there is something slightly fucked up about a justice system that hands out such a long sentence for something that can generate so many column inches about exactly what was wrong with the offence - undoubtedly something is wrong with it, but that sentence is twice as long as some people have received for murdering their spouse. Or two years longer that the bloke who threw acid at Katie Piper's face. If we're going to talk about victims, I would not particularly wish to put the victim of this case in that category.
