Forgive the ramble on, but countless hours reading about the wonders of CRM and its ilk has sometimes led to this wonderful concept of "empowering" the first officer so much that some see this as full authority to challenge the captain's every decision regardless if the questioning is a valid flight safety matter or not. This is not conducive to the principles of flight safety.
Well said, Sir.
It would be well for First Officers to actually realise just whom is in charge of the airplane...and for those slightly challanged, a hint....it ain't them.
