I just created a community to mirror the subreddit /r/moderatepolitics. The subreddit and Lemmy community are aimed towards a wide range of voices, but require participants to act civilly towards each other. Besides that, the goal is to keep the rules as light as possible to foster healthy discussion.
I had previously thought about hosting /c/moderatepolitics on its own instance, but it turned out to be far better to host on an existing instance.
