Well, after 30 years in R&D I'm yet to meet a researcher worth his salt who would agree to work in sales. Administrative/careerist types might, but they have never been much of researchers. Although, two more individuals come to mind - they had to do it after a layoff, but one jumped the sales ship at the first opportunity, and another has never been a researcher to begin with. You must be a rare bird.
A veiled insult is still meant to be an insult; you aren't nearly as stealthy as you imagine. You and I do not share the same value system so it isn't surprising when we find a point of disagreement at FR.
