It isn't clear to me that the connotations of "oversensitive" as it's used here are justified. Some people suffer, to greater or lesser degrees, in situations that I don't. That doesn't necessarily make them oversensitive, or me insensitive.
There are some things we, as a culture, are more sensitive to now than our predecessors were. That's not necessarily a bad thing.
I don't believe a rational person, in a situation where honesty causes suffering, necessarily prefers to be honest.
All of that said, I certainly support discouraging people from suffering, given the option. And I support discouraging people from claiming to suffer when they don't. But I don't support encouraging people to keep their mouths shut when they suffer. And I suspect that many social structures that ostensibly do the former in reality do the latter.
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.
