Do you believe that it is appropriate for the "ivory tower minds on the
committee" to refer to those who dismiss their points as "narrow minded"
when they explaining their points of view? Personally, I do not believe
it is; just as I don't think what you said is appropriate, but I would
like to have your opinion.
