It sounds to me like the poster did the emotionally intelligent thing of reading a room and realizing a flame war was about to break out, and thus put in the labor to prevent it- which is a really normal thing for humans to do in social dynamics. It's literally a leadership quality. Later, this poster comments that it was emotionally exhausting- not a complaint, since I don't see them blaming anyone for their exhaustion besides themselves.
