Some of Slate's French collaborators dissected this notion is a piece called "Dominique Strauss-Kahn Conspiracy Theorists Are Embarrassing Themselves," which I recommend you read. The authors make the following important point:
A similar point is made by the French feminist activist Magali de Haas in an interview in the weekly L'Express. The article is in French, but de Haas says that all the attention is being focused on DSK and his tragic downfall, rather than on the victim of the alleged crime. De Haas points out that many French people see this at most as a case of a lady's man going a little too far, instead of the serious crime he is accused of, and tend to think of sexual violence as some sort of joke. De Haas reminds readers that an estimated 75,000 women are victims of sexual assault each each in France, and concludes that DSK is not being accused "of an affair of morals, but a crime."
