Jon Pretty sounds like a complete creep and yes, based on this account, a predator. That being said, there is a court and criminal justice system for a reason. While I empathize with the author, and utterly despise the archetype of high-status men who use their status within programming communities as a tool to target women, I find the nature of these kinds of posts to be counterproductive. Therapeutic to the author?…
I only kind of agree. In this case a Chinese woman living in the USA apparently got raped in Germany 3 years ago. To involve law enforcement she would have to travel to a country where she doesn't speak the language, to make an accusation for which she has no evidence but her word, against a man who lives in another city. What, exactly, do you imagine that the police are likely to do with her report? I hate the court…
It’s also interesting that this scenario would have probably been more unlikely in the past. Before the “sexual revolution”, an educated woman would never sleep alone in the same house as an unmarried man, for fear of her “honour” being maligned. That set of cultural values had its (massive) problems, but in some scenarios it actually worked better than the current one, effectively forcing women to avoid dangerous situations.
