They can do that within MN. However, outside the State, it will quickly become a $hit show for MN as its teams and athletes are barred from competitions. Fed funds will dry up rapidly for governing bodies and schools that allow men to compete in women’s sports. The best female athletes in MN will not stay in that State, nor will top female athletes choose MN universities if they have to compete against men. They can attend schools elsewhere and be competitive against other females.
Yup—cut off all federal education aid to the state of MN.
Win win.
