Some threads get hotter with every person added to them. Each reply is partly written for the audience, and nobody wants to back down in front of twelve people.
In those cases the most useful thing you can send to the group is short: "I'll sort this with Dana directly and post the outcome here by Friday."
Then actually do it. One call or one direct message, where the person can say "fair, I overreacted" without an audience. Afterwards, post a two-line summary back to the group so nobody feels shut out.
This isn't about hiding the disagreement. The decision still lands in the thread. Only the arguing moves somewhere quieter.
We cover when to do this, and when it backfires, in our guide to calming a heated email thread.
