When do you stop ignoring fans?

The umpire is not responsible for anything that happens outside the field, neither is either coach/manager.

The best way to handle an idiot like in the OP is to put the players in the dugouts, call the TD or whoever and refuse to restart the game until the PITA is gone.

If the umpires are mangling the game through rules misinterpretation, the manager(s) have an outlet, protest the game.
