Rape is about control...not about sex.
However.
Whether a woman is a hooker on a corner in a bad area of town, or a nun in a habit....in the same area....they are putting themselves in a situation - a known "dangerous" area - where they could be harmed, regardless of how they are dressed. Though they are in no way responsible for being raped....if they hadn't been in that specific area...they wouldn't have been raped, at least not there. They put themselves in a potentially dangerous situation, and they are responsible for doing so.
This is no different from a missionary going into an area extremely dangerous to anyone not of the "local religion", just because the missionary feels the "call to convert natives to Christianity". The missionary is captured, tortured, and/or raped, and Special Ops guys are sent to rescue them, before the missionary is murdered thus severely endangering rescuers too...because the people "back home", wherever home is, want their Missionary loved one back.
Or a journalist, going into a dangerous situation all because of the "story".
Regardless of why an individual goes into a dangerous situation, they must realize that they elected to do so...and also realize that bad things can happen, no matter how good the intention.
If an individual persists in doing so....they should at the very least, TRY to minimize their presence by looking as inconspicuous as possible.
To not do so....is just stupid.
