I had one engineer escorted to the gate when he went off on a rant about George W Bush, and blurting “*bleeping* American bastards” during a meeting. Yes, this person was a citizen born in the United States. This was at a refinery in a northern blue state owned by a family that the left insanely hates.
You should have told him what Lee Iacocca said one time when he was firing an enfant terrible engineering manager at Chrysler. A defender said the guy was an engineering genius, he was just terrible with people. Retorted Iacocca, "Well, that's too bad, because that's all we've got around here."
