Knowing what I know now, I'm less inclined to explain it in terms of conscious mechanisms (I don't want to do work -- or I don't want to go to bed -- so I procrastinate by seeking out wrong people on the Internet so I can tell them they're wrong) and more inclined to explain it in terms of subconscious mechanisms. Except I don't know how the latter work, or how to talk about it, or whether that even applies to me because my mental health is "not that bad". This doesn't tend to happen to me when arguing about anything work-related, and it doesn't even always happen when arguing about politics. That, I think, has less to do with the content, and more to do with how invalidating the other person is being (which is why the Mozilla code of conduct discussions ruined my ability to do much work for a few weeks -- but that's another post I'm still writing); while there are some technical communities where emotional invalidation is common in technical discussions, I'm fortunate to be in one that's not like that. (It's happened a few times in work-related discussions at places where I used to work; essentially hasn't happened in those discussions in the past year, though.)
I don't recall being actively invalidated or dismissed as being a big part of my early life (although being ignored sure was). I'm almost tempted to posit some sort of collective memory shared by abuse survivors that would explain why it's so upsetting to me to feel like I'm actively not being listened to or not being heard (when someone replies to what they think I said, or to what I represent in their mind, rather than what I said), when I don't have clear memories of having experienced that early on in life. Then again, there's a lot I can't remember.
Does anyone have ways of explaining / thinking about this kind of thing that doesn't step on anyone else's feet? I'm not sure any of this is even understandable; hi.
