Sometimes there is just no calming anyone down. Sounds like they have already formed their opinions. And given that, inviting him in for a beer is probably not going to help. Maybe if you had been able to do that before the blow up it would have been okay, but things are not likely to change I'm afraid.
Of course, just before leaving, you could drop a nice pair of new red panties into his wash. Let him explain that to his wife! Not to mention the pink tinge to all of his underwear. (Not that I would ever recommend a revenge tactic as being a solution to the problem.)
