Sounds to me like an old geezer who can't figure out he needs to speak up. I would also call Flight Standards and the Ethics committee and let them know what a pompous a$$ you are and what a unsafe environment you create in the cockpit. Would also fill out a ASAP report at the first available chance. Good luck with that one at the disciplinary hearing. A phone call to the FAA hotline 1-800-FLY-SAFE goes along way a pushy belligerent overbearing captain if the company will not take action. All you have to do is mention "unstable".
