That would also be sufficient to abandon the definition. But no, I mean she is actually are physically safe and the guy is being creepy as @#%#. Either the recipient of the creepiness or an observer can both legitimately call that behavior creepy even if the victim of it neither feels nor actually is physically unsafe.
I'd say that the target can legitimately state that the guy's behavior is making her uncomfortable (assuming that this is in fact the case), and/or tell the guy to buzz off and have this enforced as necessary. Either the target or any third party can legitimately caution the guy that his behavior could be interpreted as "creepy" (i.e. at least mildly threatening) by others.
However, I would not use "creepy" to describe all instances where someone is being merely bothered by someone else; nor would I want to have a fixed cluster of behaviors be regarded as "creepy", regardless of the target's actual feelings and reactions. Thus, I'd say that defining the above as not-creepy is in fact very reasonable.
The above definition conveys concepts that aren't even intended for use in 'thingspace' as opposed to 'political space'. Specifically, the assignment of blame and responsibility.
Um, no. Physical causality is not the same as appropriately-assigned blame and responsibility. Even then, I could easily rephrase my definition as: "Person X's experience and overall disposition causes her to feel physically unsafe to some degree, upon being exposed to some peculiar attitudes and behavors on Person Y's part" and this would not change my preferred policy.
One of the lessons highlighted in the thread "Less Wrong NYC: Case Study of a Successful Rationalist Chapter" is Gender ratio matters.
There have recently been a number of articles addressing one social skills issue that might be affecting this, from the perspective of a geeky/sciencefiction community with similar attributes to LessWrong, and I want to link to these, not just so the people potentially causing problems get to read them, but also so everyone else knows the resource is there and has a name for the problem, which may facilitate wider discussion and make it easier for others to know when to point towards the resources those who would benefit by them.
However before I do, in the light of RedRobot's comment in the "Of Gender and Rationality" thread, I'd like to echo a sentiment from one of the articles, that people exhibiting this behaviour may be of any gender and may victimise upon any gender. And so, while it may be correlated with a particular gender, it is the behaviour that should be focused upon, and turning this thread into bashing of one gender (or defensiveness against perceived bashing) would be unhelpful.
Ok, disclaimers out of the way, here are the links:
Some of those raise deeper issues about rape culture and audience as enabler, but the TLDR summary is:
EDITED TO ADD:
Despite the way some of the links are framed as being addressed to creepers, this post is aimed at least as much at the community as a whole, intended to trigger a discussion on how the community should best go about handling such a problem once identified, with the TLDR being "set of restraints to place on someone who is burning the commons", rather that a complete description that guarantees that anyone who doesn't meet it isn't creepy.
