Hm. Looooootta misconceptions to go through here. I hope y'all appreciate that I'm staying up basically all night to write this.
Saying women can take measures to protect themselves in the present culture is trivially obvious. Women know this better than you do. At the same time, it's simply wrong to make that the first and only line of defense against rape.
The line of defense that folks like leon1122 are probably most familiar with is deterrence through criminal punishment. He's right that people still rape despite the heavy sentences, but deterrence functions through *certainty* of punishment as well as severity, and the certainty of punishment for rape is absolute shit, for various reasons. So improving how the criminal justice system detects and handles rape is one important (albeit difficult) goal. (Re: Octavious' comment, this should *not* be about lowering the standards of justice to convict more people--but there are also ways that the standards of justice are lowered in ways that harm rape victims.)
Now, let's talk about education. Most of the commentary in this thread has taken the view that said education is all about rape and not raping, and must target either the depraved rapist or the rape victim who was "asking for it." Hence the objection to broad educational outreach as "seeing all men as rapists" or "blaming the victim." But that's an absurdly narrow and simplistic paradigm.
There *are* rapist rehabilitation programs, with varying degrees of success (which complicates the "rapists are just inherently irredeemably evil, so teaching them is futile" canard), but just as most people are not rapists, most people are not targeted by rapist rehabilitation programs. Meanwhile, it's possible to note that the hypothetical woman who walked alone through a dark alley at night with her tits out and got raped could have exercised better judgment, but she's also a miniscule corner case where rape is concerned--so not only is victim-blaming callous (said hypothetical woman still didn't *deserve* to be raped), it's also completely ignorant of most rape victims' experiences.
Finally, rape should not be viewed in isolation; it's the worst (or nearly the worst) outcome on a whole spectrum of unhealthy behaviors related to sex and intimate relationships. Most of those behaviors are not nearly as bad as rape--many of them aren't even illegal, so you can stuff your nonsense arguments about what people have *a right* to do, because that doesn't make it *right* to do--but the same educational efforts that target rape also frequently target other behaviors. (We can also talk about the variety within the set of behaviors that count as rape, but it's not immediately relevant here.)
So instead of viewing rape education as trying to prevent a male rapist brute from raping a scantily clad female rape victim, we could (for example) look at it in terms of *people* who might encounter or witness signs of danger or abuse in a relationship, and educate them on that basis. Critically, this involves third parties in the prevention of rape and abuse--bystander education is a thing, people! Preventing rape is not solely the job of the would-be rapist and rape victim; it's a group effort to construct community norms like "see something, say something." This is just one kind of education, there are plenty of others.
Ideally, and this may be just my inner wild optimist talking, reframing things in this way could also help us get past the stupid, divisive, pointless Oppression Olympics stuff about whether women are oppressed because more men rape, or whether men are oppressed because more women abuse their spouses, or whether feminists are privileged, or what-the-fuck-ever. Identity politics is sometimes a useful paradigm, but when it turns a discussion about *preventing rape and abuse* into a flame war between feminism and men's rights, it can fuck right off.
We're on the Internet, so I'm looking forward to a hundred misunderstandings, nitpicks, and insults. But I hope this helped at least one person break through the fog of talking points. And hey, I'm no expert--I just pay attention sometimes--so I'm down for more learnin' if I fucked up the explanation somewhere along the way, or forgot something important.
