How to talk to a referee

[hooper]

A question from the coaching side of my brain...

We had a game recently that was very physical. The game was called VERY loosely by the refs, especially in the 2nd half. (I think 5 or 6 total fouls were called in the 2nd half.) This was a 7th grade game. Kids were flying all over the court, getting knocked down, elbowed, and, on more than one occasion, coming out of the game crying (something that just doesn't happen with this particular team team) and welts forming on arms, necks, heads, etc. I don't fault the refs for favoring one team over the other, but the level of play was allowed to get so rough and out-of-control that our team discussed forfeiting the game because we were concerned about someone getting seriously injured.

Question: Other than asking the referees to call the game closer for safety reason (which I did, but seemed to have no effect), what's the best course of action here?
