and i commonly have parents look at me and DH like we are crazy when we cheer for our team AND the opposing team BUT usually by the end of the season the other parents are doing the same. it is not about who wins or loses - it is about the kids having fun, learning something new, and being socialized and well rounded. not to mention, sooner or later your kids may fall together on the same team, class in school, etc. do you really want them not liking each other because of who their parents are. I'm sure you would think it unfair if your child was the one being looked at negatively because of who is mother is.
