I have some experience in online discussions, even of very deep, complicated, and nuanced discussions. Email discussion lists can work well for those. Usenet could as well, back when I was using it.
A medium that mostly has short messages, such as the fediverse, is not good at it in my experience.
Regardless, any medium requires some form of moderation to keep flame baiting, trolling, and outsiders with no stake in the topic from derailing the discussion.
