I feel like this would just encourage the drama to continue?
Like... most of the time when drama happens, it's because people won't just leave it alone. Everyone wants to jump in and give their two cents on the issue or say "YEAH!!! THIS!!!" even though everything of note has already been said. There are people on this forum who practically never post except when somebody they dislike has said something they disagree with that leaves an opening to "take them down a peg". Springing up like mushrooms because they basically just lurk except when there's drama, or they get told there's drama on a discord or similar and jump right in.
Sometimes the only way for the drama to stop is to have somebody say "Can we just stop talking about this off-topic sideline?" or "Look ,we're obviously not going to agree on this, let's just drop it". The only times I've ever effectively managed to resolve thread drama, it's been by taking it to DMs or discord where, uninterrupted and without an audience to exaggerate what's been said, or "agree" in a way that misrepresents the actual feelings on each side, the subject can be talked through and an understanding can be reached. Sometimes the understanding is "We can't agree, so let's just leave each other alone," and sometimes it's more productive like "Oh, I see how that was upsetting! Sorry! I get where you're coming from now."
I'm not sure how moving the drama into another thread so everyone can talk about it more really helps anyone, it just satisfies a desire to wallow in the drama and pick it apart and draw it out. It's just a way of having a tool to tell people you want to shut down, "I think you're being dramatic and that your opinion is irrelevant, you should go sit on the naughty step." while giving it a veneer of responsibility that makes you look like a good citizen just keeping the forum tidy! Do you really think moving a trans person who is upset about JK Rowling and transphobe defending her into another thread will result in anything more than just insults being flung? It's not going to lead to reconciliation; it's just milking the drama for entertainment.
I get that when the resolution to the drama happens out of view... or like... the drama is never resolved, or the drama ends before you have the chance to work through your feelings about it or voice your opinion on it, it can feel frustrating... but that's how things have to be, sometimes. It's like how a 24 hour news cycle dwelling on every last little detail of an event and social media wanting every single celebrity to give their opinion on it might be entertaining and appeal to human nature... but it's not healthy. If you do need to scratch the itch, take it to a private discord to get it out your system, or even... talk to the people in private, try to understand on a more human level outside of the public circus.
