The group of women Cosby allegedly assaulted functions almost as a longitudinal study — both for how an individual woman, on her own, deals with such trauma over the decades and for how the culture at large has grappled with rape over the same time period. In the ’60s, when the first alleged assault by Cosby occurred, rape was considered to be something violent committed by a stranger; acquaintance rape didn’t register as such, even for the women experiencing it. A few of Cosby’s accusers claim that he molested or raped them multiple times; one remained in his orbit, in and out of a drugged state, for years. In the ’70s and ’80s, campus movements like Take Back the Night and “No Means No” helped raise awareness of the reality that 80 to 90 percent of victims know their attacker. Still, the culture of silence and shame lingered, especially when the men accused had any kind of status. The first assumption was that women who accused famous men were after money or attention. As Cosby allegedly told some of his victims: No one would believe you. So why speak up?

But among younger women, and particularly online, there is a strong sense now that speaking up is the only thing to do, that a woman claiming her own victimhood is more powerful than any other weapon in the fight against rape.
