There is a balance on this issue. For one it seemed like in the thread in question the woman appeared to have been drugged, or at the very least deceived into taking too much to drink. (though it does sound like she has been drugged as being aware of what was happening but unable to move/object). This is a violation of trust and wrong anyway you slice it.
But if a woman went to the place knowing drugs were used, and planning to use them, knowing that sex was a possibility as everyone was high and inhibition were low, and it was morning after regret that would be different. But that was not what was expressed here.
However there is some interesting side take (insight) on the guy who committed the rape. It appears evident he didn’t realize that there was anything wrong with his actions that night as he sought out a second date with her. What he did morally may or may not have hit him when she denied him a second date after he reflected on how this very successful first date (home run), was not followed up by a second one.
But ‘if’ it hit him how much and how deeply he hurt the poster, if he made that realization, he has to deal with the ramifications, and that can be very hard to deal with. One such way is convincing yourself that ‘hey she was asking for it’, what did she expect and blaming the other for the offense he committed. It’s his way of dealing with it.
People who feel that way (she was asking for it), may be very much like the rapist above. Either they don’t have the knowledge of just how damaging it is to rape another (yet), or they have done such an act and need to justify it to themselves and perpetuate the lie to the unknowing that ‘she was asking for it’ is a viable defense. So if this case the pitted poster (which I am not saying it is) he deserved pity (as long as he did not cross the line), he would be so obviously morally wrong that it is a cry for help.
