I’m not actually familiar with that book (I’m guessing it’s a book?), so unfortunately I can’t have much of an opinion on it! That said, I’m definitely skeptical off the bat of that quote you provided. Rape can certainly look “at least slightly suggestive” of consensual sex at times, particularly if the victim was coerced into giving a nominal “yes” as opposed to overpowered by force. People don’t understand that sexual assault doesn’t always look “violent” or “forceful”; it doesn’t need to in order for it to be sexual assault.
What do you think of RAPE IN THE CRIMINAL JUSTICE SYSTEM by Bryden David P and Lengnick Sonja, part 3 that talks about false reporting of rape cases? They argue that reports of false rape occur more often than statistics note, and may also suggest some victim blaming. "...we concluded that in most if not all such cases the woman's behavior is indeed at least slightly suggestive of consensual intercourse." I enjoy your blog, so I would like to know what you think if you have time.
