The bigger point is that it falls into the same bucket as criticizing any civilian leadership decision. You can raise issues, you can argue your point, but at some point, the decision has been made and you are expected to salute and follow orders. Especially for a first sergeant who is responsible for getting the rest of the squadron on-board. Just as we all bitch about losing morale patches, or ROE changes, or the giant witch-hunt for sexual predators...but at the end of the day, you are expected to take off the morale patches, follow the ROE, and clean the Maxims out of your desk.
You can hold whatever personal opinions you want, but when you represent the Air Force, especially in a leadership capacity, you must also represent the Air Force's official policy on these things.
