I think what posters here are probably skeptical of is how women who have fantasies of rough sex can be interpreted.You quote me being surprised that a number of posters seemed aghast that anyone thinks women have such fantasies and I don't think they should be.
Fantasies tends to exist within limits. When a woman reads a romance novel or imagines a sexual scenario where the hero throws the woman down and ravishes her, this exists with a load of controlled, safe context. For instance, that the reader knows the hero is ultimately a good guy and will come through for her for a happy ending, and/or the woman in this situation is actually interested (which can be a sort of meta-consent, in that the character may not consent, but the reader is aware that she wants it deep down) or it's generally going to turn out well for her.
But these contextual limits and safety do not exist in a real world situation. There is no certainty of a narrative happy ending and that the woman will not be allowed to truly suffer or feel pain. The man is not going to be known to be a good guy. Stripped of the safety of the fictional fantasy, it will almost certainly just be terrifying and humiliating for the victim.
A woman with such a fantasy could approximate it for fun - for instance roleplay or rough sex with a consenting partner. I guess there could be more risky behaviours such as seeking out and trying to induce much less safe partners into aggressive sex - but if a gets what she wanted, it's sort of consensual. Or, more prosaically, the fantasy of being ravished is just that, and the woman never has any inclination to experiment with it in real life. There potentially are a few women out there who might genuinely be turned on by completely involuntary assault. Does anyone here believe there are more than a handful of such people, and and that they wouldn't likely have significant psychological problems?
This, then, is the problem with thinking women have fantasies about being sexually assaulted. They might well do, and maybe most of them have at least one "rape fantasy" at some point in their lives. But even if so, they almost certainly do not ever want men they meet to be highly aggressive or sexually assault them in real life, because real life isn't a fantasy.
