comments we think contribute negatively to LW,
is a dangerously broad category. For example, one might start downvoting all comments from gender X because we think we need less of that gender because they "contribute negatively". Or we might start systematically downvoting a particular person even when they make an entirely valid point, because they are "part of a problem" and need to be chased away. No, downvoting should solely be a measure of the degree of accuracy and relevance of a comment to settling the empirical question at hand.
As we become politicized, we will find ways of justifying political actions against people on the "other side", and having a really broad category like "contribute negatively" will just make it really easy for us to do that. Our brains do all this automatically.
At some point we really do have to enforce community norms to prevent the level of discourse from deteriorating. Antisocial and obnoxious behavior are perfectly valid reasons to downvote a comment, I have a hard time believing you really think they aren't, and I'm reasonably confident that most of LW is okay with the idea, judging by other comments I've seen receive downvotes (not to pick on him, but Annoyance has gotten some of this) for no obvious reason other than tone.
The issues are where to draw the lines, and how to handle it when the community is sh...
It seems that LessWrong has a nascent political problem brewing. Firstly, let me re-iterate why politics is bad for our rationality:
Politics is especially bad for the community if people begin to form political factions within the community. Specifically, if LessWrong starts to polarize along a "feminist/masculinist" fault-line, then every subsequent debate will become a proxy war for the crusade between the masculinist jerks and the femenazis.
Alicorn has contributed in several ways to the emerging politicization of LessWrong. She has started name-calling against the other side ("Jerkitude" "disincentivize being piggish"), started to attempt to form a political band of feminist allies ("So can I get some help? Some lovely people have thrown in their support,"), implicitly asked these new allies to downvote anyone who disagrees with her position ("There is still conspicuous karmic support for some comments that perpetuate the problems"), and asks her faction to begin enforcing her ideas, specifically by criticising, ostracizing or downvoting anyone who engages in a perfectly standard use of langage and thought: modeling the generic human female as a mechanical system and using that model to make predictions about reality. She has billed this effort as a moral crusade ("unethical"). I am sure she isn't doing this on purpose: like all humans, her brain is hard-wired to see any argument as a moral crusade where she is objectively right, and to seek allies within the tribe to move against and oppress the enemy. [notice how I objectified her there, leaving behind the language of a unified self or person in favour of a collection of mechanical motivations and processes whose dynamics are partially determined by evolutionary pressures, and what a useful exercise this can be for making sense of reality]
We should expend extreme effort to nip this problem in the bud. As part of this effort, I will delete my account and re-register under a different username. I would recommend that Alicorn do the same. I would also recommend that anyone who feels that they have played a particularly large part in the debate on either side do the same, for example PJeby. That way, when we talk to each other next in a comment thread, we won't be treating the interaction as a proxy war in the great feminist/masculinist crusade, because we will be anonymous again.
I would also implore everyone to just not bring this issue up again. If someone uses language in a way that mildly annoys you (hint: they probably didn't do this on purpose), rather than precipitating a major community feud over it, just ignore it. The epistemic rationality of LessWrong is worth more than the gender ratio we have. A 95% male community that manages to overcome a whole host of problems in instrumental and epistemic rationality is worth more to the world than a 80% male community that is crippled by a blood-feud between a feminist faction and a masculinist faction.
