I encourage efforts to maintain high standards of reasoning, and fairly explicit reasoning. In evaluating harshness, we need to strike a balance between at least three goals: 1. clarity of thought, 2. creating proper incentives for quality contributions which requires punishing mistakes / undesirable contributions, and 3. creating a friendly and respectful atmosphere.

For the record, calling Annoyance's comment, "unnecessarily harsh" was meant to be a minor criticism. There are many factors to consider, in this case I would have suggested that Annoyance replace "Logical fallacy" with "Nitpick." Also see my new comment for Annoyance.
