They need to be put in perspective. To raise the bar of standard for a competitive match where contact results in pain and injury, seems a bit unfair, when the same language is used in the hallways and public sector as casual communication. I don't think the 10 minute rule has decreased language in Michigan. I don't produce cards from my pocket like Harry Houdini the first foul word I hear. Girls today are not tha sweet memories of our youth.
Girls love to argue and get value through communication more than boys.
Boys would rather get revenge. I like your tactic. I prefer to negotiate some control on behavior such as this rather than punish it. They don't agree with all of them. But I think that they will all agree that the players know the rules when they step on the pitch.
