I usually don't comment on this stuff, but the hair pulling incident brought up some issues I am seeing in high school girl's sports. I do see officials making calls they would NEVER make in a boy's game. And it seems parents, coaches, and athletes are OK with that for the most part. But there is the occasional official who works both girls & boys games and doesn't differentiate between the two genders.
We had girl's rugby game this past spring where a lot of player's from the other team were getting hurt. Some of our girl's tackles looked like NFL highlight films. They're really I nice bunch of kids- they just like to hit and they're good at it. The best is this little Puerto Rican girl, all 5'2" of her! The coach came out onto the field and admonished the ref for "letting the game get out of control" and threatened to pull his team off the field. To keep the game going our coach actually had to tell our players to bring them down a little easier, and took our 5'2" assassin off the field. It was a playoff game to boot.
