[This post has been renamed from "Desilencing", pending changing what I call the action.]
edit 2019-06-25: this post is tone-deaf about ways people who experience the more common and dramatically stronger silencing forces of prejudice would see it. The insight here appears to me to be valid as an incremental change in an environment with low but nonzero hostility; it's not as immediately relevant when a very large change is needed. I have changed my vote on this post to a downvote.
I often find that I filter my urges to give feedback, especially negative feedback, in public.
For example, when downvoting someone, I often feel an urge to say why. But then I hesitate because I worry that they will feel insulted, and attack me for my trouble of explaining myself.
This fear is not unfounded. sometimes when I say why, people do in fact challenge it.
But if I was on a discussion board with a bunch of slightly different myselves, and I never gave the other mes feedback, I would never get any feedback from them.
So, some semi-random fraction of the time, I say the thing anyway, in a short message with little overhead for me. I'm taking some risk, because then I say things that might get me in a fight. But people get more detailed feedback, instead of simply being ghosted or downvoted away because I'm scared of the fact that it's unsafe for me to be straight with them.
So when I say I'm "de-silencing" myself - this is what I mean.
I call it "de-silencing" because I do it to break the attractors that silencing forces on me create. Some non-negligible portion of the time, those forces do specifically intend to silence people. And this technique would not work if someone was specifically out to get me.
This post is itself a de-silencing post: I'm not putting as much effort into it as I think would be necessary to ensure it gets a good reception.
