They arent boys why are you insisting on comparing them to boys?
I compare them because they are athletes. I don't care if my team chooses to cheer and dance in the dugout. I don't judge them as better or worse teammates because of it.
I have 2 main expectations of my teams, play and practice hard, and pay attention to the coaches, the game and what your teammates are doing. If a kid can pay attention and give me her/his all, thats what I want. How they dance and sing doesn't factor into my opinion of them one bit.
And yes boys and girls are different, but not in some of the ways some coaches think. I have coached with guys who have low expectations of the girl's ball playing because you know they are girls. And guess what, their teams play below their ability, but boy could they cheer and dance.
