Yeesh,
Though I do know there are "fake rape" cases, often done for financial gain, they are few and far between. I also do see it as a "women are too dumb to make the distinction" point. A little story.
When I was 14 years old, thus possessing far fewer adult mental and judgment faculties than the woman posting, I was trying to get on a skilift that the operator had overloaded. Instead of having the lift neatly hit the back of my thighs and sitting down, I got hit in the butt by a middle-aged man's knee, and I pitched forward. Instinctually he grabbed for me, thinking I was going to get nailed in the head... now this man ended up grabbing me by the breast and shoulder and half pulling me onto his lap until I yelled "LET GO!!" (not because he was 'assaulting' me, but because it was obvious he wasn't going to get me all the way up, and the lift was getting higher, promising a farther drop when he did lose his grip).
Now even to my fourteen year old mind, this incident was VERY CLEARLY an accident caused by a well meaning attempt to prevent me from injury due to some carelessness on the part of the operator. I could have said the bad man touched me in a bad place, but why?
The fake cases tend to be the fake cases, and usually the faker doesn't come on internet websites to announce her trauma because she is busy negotiating legal fees, plus, again, why? If you are suffering no trauma and have no reason to warn others, why advertise? Women who do this tend to have suspicious records of suit and accusation activities and posting on a website merely advertises this trend for the next time.
Women are by and large, intelligent enough to distinguish between unwanted sexual advances and pure accidents, and there is generally an entire mood to the encounter.
Additionally, details of this poster's encounter seem to lend support to her story, though was certainly under no obligation to share any details. It is one thing to warn or discuss generally; it is quite another to discuss graphic details with strangers. The fact that the instructor's lack of a wetsuit on the dive in question (as compared to the others) was a significant detail, for instance, leads me to think there was a little bit more going on here.
There is 'requesting both sides of the story' and there are other sentiments that, while claiming a desire for both sides, seem more to imply that the woman is likely hysterical and the poor man is the victim unless she can detail out the story in significant enough detail to satisfy the onlookers. That seems wrong. Think of it this way; if you had video footage documenting this incident, and upon viewing it, you realized she was absolutely 100% in the right, and a very real emotional trauma as well as a definitive sexual assault was committed, would anyone feel a smidge guilty about the tone of their posts?
