This isn't a recent post, but a great one nonetheless that discusses some preliminary studies on what proportion of the young male population has engaged in rape. Two studies are discussed where men were surveyed about past sexual activities that involved the use of threat, force, or intoxication to gain compliance of their victims without consent. The word rape is not used in the survey, and that is likely why the men felt comfortable self-reporting these activities, though it's unclear if any men declined to report truthfully. The conclusions of these two studies were that roughly 13% of the male population have raped, and between 4% and 8% are serial rapists. These numbers could potentially be even higher if some men declined to answer truthfully. Of those admitting to rape, only about 30% reported using force, while the remainder went for intoxicated victims in what are likely to be socially sanctioned acts of rape, since the guy can easily claim confusion about her consent since she was not in her right mind. That means a large proportion of guys opportunistically take advantage of intoxicated women because they know their friends won't question them about it. Anyway, have a read, this is a great post.
