This is good article from few years ago: Dealing with Toxicity in Online Communities
This is a challenge of how to be respectful of different opinions but not allow conversation to deteriorate into chaos.
One topic that many people in my home town community can be upset about is housing development projects, which there is a lot of resistance against. People are very attached to small town rural culture but don’t generally seem to want to help with improving housing affordability for the general public, which is a problem.
There can be some good discussions at public community meetings but often some folks can take over a whole meeting if the public officials running those allow that to happen. Some meetings are more official than others and are more professionally moderated with time limits on public comments.
Leadership is important for there to be consistent presence from a community leader and/or moderators. I believe in people having opportunity to speak freely but with accountability.
