@shit-piss-love said in What Makes a Healthy Community and How to Deal When it Isn't:
When someone starts to drift from civility in interaction with a community they actually care about, it’s because their emotions have got on top of them. That’s not a Bad Thing. Trying to climb on top of your brain is just what emotions do. And we apes like that and it can serve a purpose. Angry Gets Shit Done. But emoting that anger has a tendency to degrade many messages, even if just as a subconscious reaction in the reader/listener. Sure, it’s galling that if I want to be as well-received as possible when expressing myself, I may have to curtail the rage roiling like stomach acid in my furious punk heart. But demonstrably, if I do that, my messaging is received far better especially by the people watching me argue with the person I want to flatten with a rogue meteor. Imbuing my words with the full force of my anger by veering off the path of civility certainly feels good and it may even totally hit right with people that already totally agree with my position but those are the people you least need to reach in a public discourse.
The issue is really that dropping civility is assuming claim to a larger portion of the emotional space in a discussion or community than you are tacitly entitled to by default. It’s the verbal/written equivalent of an animal turning to their largest profile to ward off potential aggressors.

With regards to the idea that emotionally-charged statements degrade the acuity of one’s argument for its intended audience, I think that this is often down to personal and/or cultural bias.
There may be good and understandable reasons for why a person’s more inclined to listen to stoically delivered arguments over emotive ones; you’ve given yours. However, I think it’s an error to suggest that this bias is universal or that it’s inherently correct.
Since we’re bringing up fascists, let me jump straight to a reverse Godwin’s Law and mention that the big famous one from back in the day was regarded as a very charismatic and effective communicator. He had 0 chill about it, though. In more modern times we have the likes of Alex Jones, who I think most of us here are likely to agree is a blithering idiot, but nevertheless one who’s depressingly successful at securing an audience. Bill O’Reilly would be another example.
There are more positive examples, such as Greta Thunberg, MLK Jr., etc. There are surely people who disagree with the messages that these famous figures espouse, and particularly in both Thunberg and Jones’ case, those who mock them for their emotionality; however, I don’t think that’s ultimately the reason why their detractors are disinclined to hear their message.
There’ve been a few recent posts on these boards that I can personally attest to having found compelling, specifically because their authors were willing to convey themselves emotionally; posts which reference personal accounts, which I deemed instinctively to be authentic and true, even without being aware of too many facts about their situation. In a number of cases, I’ve reached out to let the poster know, ‘I know how you feel.’ And I think those moments can in fact strengthen a community, so I don’t think that one in which we uphold communications that are drier and purely factual is better.
Of course there’s a balance, and there’s a time and place; I try not to bleed all over people uninvited if I can help it. If I can’t help it, I try to later reflect on whether the behaviour was appropriate, or if I might’ve done better to instead extract myself from the situation. Emotions can be harnessed and weaponised, for better or worse; a person can appear suspicious, or unsafe to others, if their communications always telegraphs a heightened level of emotion. But I think the opposite is also true, and those who appear to feel too little can seem insincere, unkind, or simply unengaging.
If your community is able to keep things civil most of the time, you can use it as a barometer both for how healthy your community is and for measuring your own emotional load relative to a topic in discussion.
I think this was an important point, so I hope I haven’t misread it.
A community should, generally, be civil. I don’t want to be friends with people who are usually negative, nor to participate in a community that usually is.
When my friends are acting in a way that seems negative or toxic, it’s a cause for concern, specifically because that behaviour isn’t like them. And in that light, I don’t treat it as a character flaw: I see that it reveals a problem that needs to be addressed. A healthy community may need to convene and weather a rough patch in order to come out the other side better able to breathe. I’ll be optimistic and say that I think that’s likely to be the case with BMD.
No one wants to engage in a community that’s consistently joyless, but most don’t have a problem resolving concerns in one that otherwise tends towards enthusiasm.
