Even if you are correct in believing I have some emotional motivation, what are the benefits to anybody of pointing it out,

I downvoted gwern's comment for rudeness and invective, but I was tempted to upvote it for pointing out to you that this post and its predecessor pattern-match to escalating conflict over a personal slight and lashing out, along the lines of other posts. Talk about becoming enemies with gwern furthers the appearance, regardless of the reality. Presumably similar considerations affected some other upvoters and downvoters.

Why care about that perception? Well, you have repeatedly expressed your frustration with unexplained lack of upvotes or the presence of downvotes on pieces you think are strong. If you are perceived as unreceptive to critique, and likely to lash out, then readers have less incentive to reply to your questions, especially when they expect you won't like the answers. This hurts you, because you lose out on feedback that could help you improve your writing and its reception. It hurts LessWrong via the opportunity costs of any improvements you might have made in response to feedback, and unpleasant drama.

I hesitated to post this comment, lest I exacerbate this local exchange or get mired in it, but I do think you could create a much more amicable relationship with respondents and get better feedback if you went out of your way to avoid the perception of retaliation. Concretely, Kaj Sotala and Yvain's responses to criticism might be good models.
