None of the above means locking doors isn't smart.
None of the above means that going to a frat party and getting drunk is a good idea.
Or getting drunk in a bar.

I think part of the problem here is that somehow, this culture has twisted things around so that the awareness that there are things one can do as a potential victim to reduce one's risk level winds up offloading responsibility from the perpetrator. As though, because the victim didn't take as much care as they could have, society is less outraged at the person who actually committed the assault. What that person did is just as horribly wrong no matter what the victim did or didn't do to try to avoid it--whether the victim took every precaution possible, or was completely careless, the person who committed rape is every bit as much a rapist. Society, though, treats it as though there's only so much responsibility to go around, so that to the extent that potential victims are capable of looking out for themselves, potential perpetrators have that much less responsibility for their actions. That sucks.
