Mods are only humans. People are always disagreeing on what is "Off-Topic" and what is "On-Topic." The definition and meaning behind what or who are trolls is a matter of debate as well. People say different things about these things and the mods are not always going to be perfect at knowing what is off topic or not. Not all rabbit trails are bad. Some things are related subjects. Some things are talked about for the use of analogies and parallels and comparisons and illustrations and examples. I compare the force to the fairy dust of Peter Pan. I would not call Peter Pan off topic if I had a point t to get across.
