"In a few cases (N I think you are misinterpreting. First, they say:
"...information was obtained about any possible unwanted sexual experiences of the comparison females or other family members"
So interpreting it as 5 of 84 women is incorrect. It's min 5 people of 84 families. Given a mean family size of perhaps 3.5 (if by "family" they mean "nuclear family", though I bet they include anyone you know about really--Uncle Bob would count, and one report per family with reports) it's more like 5 out of 294 people, or 1.7%. And I don't think they share their exclusion criteria, which isn't a good sign. And there's a significant selection bias given how they recruited (in a newspaper, for people who have the free time and/or low wealth enough to want to do a study, and in particular on female growth and development).
I think your comment is getting attention because you're offering an idea that people like, and some anecdata to back it up. It's a classic problem of the modern world, things that people want to believe get a lot of attention, out of proportion to their actual frequency. I think you, and others here, want to believe the situation is worse than it is, or worse than the data here warrant believing, because you're going to get rewarded for acting as if the appealing idea is the case. I don't mean you are sitting there, consciously thinking that, but the rewards (here some updoots on HN) shape your behavior behind the scenes anyway. This is how we get news that paints a grotesquely distorted view of the world: people want to hear about how a crazed soccer mom murdered all her kids in the bathtub, and critically it is profitable. They don't want to hear that everything was fine in Peoria, IL last night.
I would bet a lot of money that the picture you paint with the study's numbers is substantially false. For one, your interpretation of the numbers they give is wrong. Second, the study doesn't appear well done. It's a little old, but it also has a lot of indicators that it isn't of high quality (e.g., lots of "p<0.05", but no "p<0.001"--see p curves). I haven't read it in detail and won't because my spidey senses say it's not worth it based on what I've seen skimming.
