"Reverse rant"

[MD Longhorn]

Berating and belittling has no place.

However, you might consider that what you consider berating might not be intended that way. You give no details, so it's hard to know exactly what precipitated this interaction. If the "veteran" is an evaluator - perhaps his delivery sucks, but it may derive from frustration. Perhaps he's said the same thing 3-4 times to this official - and nothing is sinking in. I can see, at that point, the veteran not wanting to hear the new guy's constant disagreements with his input. (Of course, it's entirely possible that the "veteran" here is just vastly lacking in tact or people skills.)
