I personally have experience in that department; I've been stalked home three times, and while traveling abroad I've almost been abducted, twice. I've had my apartment broken into, seen my personal objects (dildos, pads, tampons) thrown about my apartment, and felt violated.
While I cannot ever say I know what it's like to be raped, I can relate on a similar tangent. I didn't lock my window and for weeks I couldn't sleep alone, I'd blamed myself and my boyfriend blamed himself too (as he'd been in the apartment last). I'd say I was in the kiddie-pool of shame compared to what a rape victim would feel, but there's something harrowing about the echo of "If I had only..." or "I should have..." And that sentiment extends to whenever I recount how I was stalked. "Why didn't you have mace?" "Why didnt you scream?" "You could have just called the cops?"
I think "rape culture" doesn't have to do with what you wear, but rather who you are. Rapists do it (mainly) because they seek control and power. I think rape culture exists in the sense that when a man is raped, he is congratulated. Rape culture exists in a way that doesn't treat both sexes equally (Lena Dunham, anyone?)
I think there's ways to discuss rape and help counsel victims to realize its not their fault without having to parade in undergarments and blame the patriarchy. I feel like doing that is sort of putting a mask on it, almost making it into a joke for those who cannot empathize.
There's a place for "rape culture" and way about doing it, but I dont think this is the way about doing it. I mean, the term "rape culture" now is like "feminism," almost. SOME (NOT ALL) arguments have made it hard to jump on board with the approach. I know I get tired of "I wanted sex, but then the next day I didnt so I called it rape" strawman-- but some people actually use that as a point.
At the end of the day, it's a huge monster to discuss because there's so many variables. The fucked up rapist, the girl who was raped, the world's views on taking care of mental healthcare (ie; how easy it is to get counseling/therapy in certain areas) and your culture's views on men/women/sex.
