> Ummmn, you appear to have missed the bit where this "unwanted sexual overture" was put in context i.e. "one or more inappropriate incidents by angels or VCs"

I think you're missing the point here. How did the survey define which unwanted sexual overtures are inappropriate? You write that this was put in the context of harassment, but how this context was presented to the respondents has a big impact on what their responses really mean. At face value, it seems like the study considers all romantic advances to be inappropriate. This seems like an overly simplistic definition, as per my example here: https://news.ycombinator.com/item?id=18225474

Asking for further context is entirely warranted. Studies like these can often be made (intentionally or unintentionally) to seem alarmist due to poorly defining categories of harassment. For instance, I was counted as a victim of sexual assault in one of my university's surveys because I answered yes to the question "have you received unwanted sexual advances in the last year?". Yes I had, but all of them were from people who ceased their advances after being denied and generally acted with respect. While there's always some element of discomfort in being put on the spot like that, I would absolutely not consider any of these instances harassment in any way shape or form. Asking someone out on a date or inviting them over for intimate contact, and ceasing all advances after being denied was considered an act of sexual harassment by this survey. I'm not kidding, if someone asked a person out respectfully, they got told no, and both parties walked away with no further contact this was considered sexual harassment. This also disturbed me because it not-so-subtly implied that I had harassed literally every person I had asked out on a date and was denied, even though I've never continued pursuing someone after being told no.
