There are all kinds of threads. This is about a specific thread type where two or more opposing points of view are discussed, mostly civilly, and no one point of view is the agreed "winner".
What generally is a more important outcome of a forum thread for you as a participant: Harmony or Clarity?
Harmony being, the participants have agreed to meet in some form of middle ground. Consensually, no one's point of view is deemed "the winner", but somewhere in the middle there is an agreed meeting of points of view.
Clarity being, the participants have agreed that they fully understand everyone's points of view. Also consensually, no one's point of view is deemed "the winner", but no one has retreated, essentially, from their point of view.
Sometimes they can exist together as an outcome, and it is quite a fruitful and wonderful result when the work to make it so happens. However, most of the time we must settle for one or the other. If you had to settle for one or the other, vote for that.
