Serena is right and wrong - mostly wrong, but yeah. There is a reason we talk about the actions of victims. To an extent, people can keep themselves out of some trouble. Prevention is the best medicine for anything. And this is something we should be able to openly talk about without people freaking out. Most rapes are perpetrated by people the victim knows and often times violence (beyond the rape) is not involved. This doesn't shift any "guilt" towards the victim. It's just as simple saying "if not for a, then b doesn't happen." Females need to know that a lot of guys are capable of this sort of thing and how to shut it down or avoid it.
With that said, this never takes away the guilt of the offenders. Any a$$hole that can do this sort of thing deserves everything they have coming.
