Sugar and spice--
When I see a thread in which I don't understand why someone's getting flamed, I realize (though I didn't for about a year) that there's some kind of history going on, that there's a background to the situation that I don't understand. Maybe there's bad blood or the flamee has been caught lying or perping or trying to disturb the peace on GC.
If more than one GCer is going after the flamee, I *know* that's what's going on!
