I see! I understand your POV a lot better. Yes, I agree. It was handled poorly. And I do think the whole situation was likely a result of the staff trying to deal with poor planning that trickled down from their supervisers. I still hold the guy responsible, ultimately. But the whole thing doesn't reflect well on the airline or their staff. Wrong fight to pick in front of a plane of customers.
This particular guy was an idiot, but you encapsulated it perfectly. They shouldn't have put their issues on the passengers and they should not have let it get to the point of violence. I should really use powerpoint for all my communications. I'm great at it. Personal, long form communications? Not so much.
