I think a little humility would go a long way.
No one is asking for, or expecting, this board to become a courtesy class - everyone is free to question, cajole, posture, and pontificate about anything under the sun, and to their heart's content.
But if I were a super (or an architect), I'd hope that my words, as a practicing professional, were given their due respect and value, especially from a group of impassioned amateurs who, presumably, care more about those words than most.
Whether we agree with the approach to agronomy that their professional duties sometimes demand of them is another question.
