EDIT: I've reconsidered this, and what I wrote here is unfair to SilasBarta. What really happened here, I think, is that Alicorn's actions inadvertantly set up a feedback loop, which no one understood well enough to shut down before it blew up here. In this post, I chided Silas for not recognizing and disarming that feedback loop - but the truth is, there were plenty of people, including both Alicorn and myself, who could've repaired the situation with a little more awareness, and this comment really didn't help.

And to clarify - what started this whole thing was Alicorn asking Silas not to respond to any of her comments, which was a strange and hostile thing to ask. In this comment, I interpreted that request by rounding it to the nearest non-strange request, which more than I thought. Unfortunately, when asked to clarify, Alicorn clarified it as literally "don't reply to comments", rather than "don't try to initiate conversations", as she should have.

Original comment below:

Ok, this has gotten painful to watch, and since no one has explained it properly, I feel I ought to overcome the bystander effect and step in. SilasBarta, you have dramatically misunderstood what is happening here. You are flagrantly violating a social norm that you do not seem to understand. Alicorn has acted in a way that is fully determined by your behavior towards her, and anyone else would do the same in her place.

When you speak someone's name and know that they can hear you, you are, in effect, attempting to summon them. It effectively forces them to listen; if in public, they may need to step in to defend their reputation, and if in private they know they're specifically being addressed. Attempts to initiate conversation are a social primitive; neurotypicals track a statistical overview of the nature, frequency, and response given to conversations with each person, and expect each other to do the same.

If you attempt to initiate conversation with someone, they give you a negative response, and you knew or should have known that they would give you a negative response, then you are pestering them. By "negative response", I mean visible irritation, anger, or an attempt to push you out of their sphere of attention without using a pretext. If you repeatedly pester someone who has specifically asked you not to, and you don't have a sufficiently suitable and important pretext, then you are harrassing them. Pestering someone is frowned upon. Harrassing someone is frowned upon, and can also be illegal if it either carries an implied threat or is sufficiently flagrant. Also, our culture assigns additional penalty points for this if you are male and the person you're harrassing is female.

So here is the story, as I understand it. After an interaction that did not go well, Alicorn asked you not to reply to her comments. This means "don't pester me" (or more succinctly, "go away"). This is one of a small number of standard messages which all neurotypicals expect each other to be able to recognize reliably and to pick out of subtext. You continued to participate in conversations Alicorn was involved in, by responding to other commenters, but every time you did so you spoke Alicorn's name, even when you had no pretext for doing so. You interpreted her request in a literal-minded but incorrect way; you failed to generalize from "don't respond to my comments" to "don't try to pull me into a conversation with you by any means".
