Blaming the victim doesn't help resolve misogyny. Instead, it simply shifts the dynamic into a "one versus all" when we really all ought to be offended by what happens. Especially when the perpetrator treats other men with higher respect (he puts on that whole misogynistic show of machismo to impress other men) and other men also have the political authority (one of them organized the whole project, for crying out loud!), the other men especially failed to stand up to that kind of talk. Instead, their silence contributed implicitly to the same consequences as victim-blaming: one person alone having to call out the misogynistic bastard. It's not so simple as "Well, she's just as guilty as the men for not speaking up!" Sure, she should have stood up to it, but with both her friend and her boyfriend complicit in the women bashing, she can't act on her moral obligation. Especially when calling out the bastard would likely shift his hate-talk onto her, not just women in general.
