So that's one concern I had as well, as well as the 'echo chamber' effect. However what I'm seeing is the more nuanced and dissenting opinions are already getting fed up and are already reducing their participation. There are people who've expressed a concern with the direction the forum has taken and much of that boils down to what takes place in GD when you drill down enough. I think the loudest voices thing is already a concern.
I also think that proper moderation may counteract that. If you *have* to remain civil or simply lose your ability to post in the politics section, will that not encourage civility? If it spills over, we can deal with that as well. Of course, I'm sure there will be some level of butthurt on occasion, but that's going to be expected if we do or don't.
#1 is a solid point, and perhaps worthy of it's own forum either way. A "2nd amendment legal/political" forum where court cases, pending legislation proposals, etc. could be showcased outside of the air fryer/chainsaw/pictures of trees sort of threads may actually get those topics more exposure.
#2 I've already touched on. It would not be Romper Room rules and would likely be more strictly monitored then GD as far as needing to stay on topic, civility, etc.
