At what point do you acknowledge fans/parents?

[ILRef80]

So, I was working a 7/8 girls doubleheader tonight and in the 2nd game we ran into an unruly group of parents. There was about 20 of them total and 10 or 12 were the type to complain about any and every call/no-call. They were screaming at us EVERY TIME down the floor. The insults were getting personal and it really angered me that they would display this type of sportsmanship in front of the impressionable girls.

Towards the end of the game, I was very close to having game management take care of it, but decided to hold off. Just a very frustrating night, I've only been a referee for 3 years but it was the worst I've seen at any level. And it was a junior high game!
