Mr. Rhyner, school districts with policies allowing transgender students to compete in sports based on gender identify require that a student consistently behave as a boy or a girl in dress, mannerisms, how they refer to themselves, everything.  A boy who wants to play a sport but gets cut from the boys' team and suddenly shows up to try out for the girls' team (like that's going to happen) is not going to meet the requirements.  Not to mention that the young woman from Haines who competed in girls' track is taking hormones to support her gender identity.  So your argument lacks logic, in my view.
