Some boys around here are playing field hockey with the girls cause there is no boys team. Even if they have to wear a skirt as a uniform.
That said, if the girl wants to play, they have to let her. We have had girl kickers in high school here.
When I played midget football there was a girl playing nose guard on one of the teams we played.
These things will sort themselves out. If the girl isn’t up to the physical demands of the sport, she will eventually quit.
What does the girl do when the boys hit the showers?
I guess in CA and MA now they can join them
That seems reasonable.
