This rule gives moderators a greater ability to control high-tension topics that get out of hand quickly. There is no longer a need for the "should we discuss politics" on CD because there is a rule stating that if it gets nasty, it gets deleted.

There are many off-topic things going on, and moderators won't read every single one, purely becasue they don't need to. However, for those cases where that kind of guideline is needed, it's available.
