I'm not arguing against the need to express sexuality in a moral way. But if we have good reason to think that sexuality (or status-seeking, the wish to redress grievances, or any of the psychology behind revenge, nepotism, etc.) is a low-level motivation, then from a eudaemonic standpoint it seems like a very bad move to prioritize denying or minimizing those motivations instead of looking for relatively benign ways to express them.
We have only a very limited ability to change our motivational structure, and even within those limits it's easy to screw up our emotional equilibrium by doing so. It's far better -- if far harder -- to come up with an incentive structure that rewards ethical pursuit of human drives than to build one which frustrates them.
I agree with the first paragraph and ADBOC with the second. Human culture contains lots of incentive structures that do just that. It is often not at all necessary to invent new ones, but rather to evaluate, choose, and tweak existing ones.
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.
