Sargee7, 
Yes, the opposing coach is a jerk. Not first time I was involved with his idiocy. 
The league uses all teenagers for umpires, and most coaches understand this and are quite even keeled. This guy isn't.  In fact, I had a run in with him 3 years ago when our boys were still in "dad pitch" at 6-7 years old .  He freaked out at our team's coach for starting the game when he wasn't there (he was 20 minutes past game time and his assistant was ok to start w/o him). 
Funny thing (maybe not so much) ,in a small town, is that his son and my oldest son are on the same booster basketball team, and his daughter and my daughter are also on a tournament basketball team. Glad for my youngest he's only got 2 kids
