Just drop it. The guy is an ass and at this point he can't see it for what it is so you won't get through to him which will frustrate you even more.

If this is the way he has always been and lasted 20 years then someone thinks he is worth putting up with. You can't fight that.

You DO NOT want to create a "him or you" situation.

I have had peers and bosses loose their s++t during heated "debates", I never react in kind but force myself to take the high road and remain unemotional and calm. End of the day I look like the mature one and whether or not I was wrong I look right because I kept my cool.

I outlasted 10 bosses in 12 years that way.

Good luck,
Scott
