I do not have a problem with refs not giving cards for foul language. If a player uses foul language she is just making herself look bad, not to mention her team, coach, and parents. I'm ok with the coach and parents handling that however they see fit.
But i would like to see the refs tightening up on calling fouls and giving cards for dirty play and making more of an effort to protect the players. Too many games I have seen the play get rougher and rougher, dirtier and dirtier, until it escalates into players getting hurt. I've seen a player be pulled from behind by her ponytail in a high school game before another similar incident became famous! No foul- probably because the ref wasn't watching even though the player pulled from behind was dribbling the ball. I think some refs have a laissez-faire attitude toward calling girls games vs. how they would call a boys game and that is particularly aggravating. One girls game I saw I feel certain would have resulted in a bench-clearing brawl had the same things been allowed in a boys game. A foul is a foul - just call it.
