A question for all the people who seem to have no issue with a girl in a boy's locker room:
Should boys and girls have separate locker rooms? Why?
A possible solution to this particular situation:
All the boys decide to "identify" as girls, and get changed in the girls' locker room. Then, all the girls will become uncomfortable in the girls' locker room, and they can "identify" as boys, and use the (now unused, except for the 1 tranny) boys' locker room.
only a true sexual pervert would think something like this.
