Yeah, but they lie about rape in about the same proportions as they lie about burglary to pad the insurance claim. I.e. about 3%.
If someone gets mugged, it feels like the first question people ask is "oh my god, were you hurt?" If someone gets raped, the first question people (in the press, round the watercooler, etc.) is "what did she do to send out misleading signals to the poor man?" We're seeing it on this thread. "Spread her legs", "wanted the part", "could have just walked out."
(Incidentally, my feeling on reading the "first person account" is that the Ansari case wasn't rape, just a remarkably insensitive man totally oblivious to the feelings of the woman he was with. And actually, at no point has the anonymous "Grace" ever said it was rape or sexual assault. I do take issue with the "not a mind reader" bit, though - you don't have to be a mind reader to know that if a woman repeatedly removes her hand from your penis after you've repeatedly placed it there, that's because the woman probably doesn't want it there.)
