It's definitely sad, but it's also honest. From a general, social perspective, women are being given a lot of hypocritical messages through media and family. Like, "Okay, you're allowed to be equal to men in theory, but we would really appreciate it if you remain compliant and innocent." Rape fantasies now seem like a perfectly logical answer to this "request" for females to remain pure whatever the circumstances.

"Whips and chains excite me" is an individual reason for a rape fantasy, but "it's not my fault" may be part of a societal concept that's much larger and more deeply ingrained. I love talking about this sort of stuff, though yes, it has a certain edge of conspiracy theory to it.
