Two questions you may wish to consider:
1) Was it necessary to "hammer" the female player in order to "knock her off the ball", or could you have been just as successful with much less aggression?
2) When a smaller school does not offer a girls program, do you believe a female deserves the opportunity to play the game without being "hammered" unnecessarily?
Keep in mind the referee's primary responsibility is the safety of the players. When a female is playing just as agressive as the males, the referee should, and usually does let them play as equals. However, when a female is not playing to their level of aggressiveness, I would think her opponents should not be more aggressive than necessary to get the job done. Doesn't this seem reasonable? If not, perhaps someday you will have a daughter in that circumstance and then you may see the light.
