Ref in Stands

[Redneck Ref]

During a match-up of our top 2 teams in league play (HS varsity game). I was in the stands as a spectator when a local college division 1 official (spectator also) just rode our 2 guys on the floor the whole game. He screamed at them on what to call, what to look for, etc...The fans around him fueled off him the whole game. As an official I was embarassed at his antics. I thought you never criticized a fellow official, especially during a game. I thought the guys did a great job. Any thoughts?
