the executive order establishes a legal definition of male and female but is not a law and doesnt compel female-presenting xx aberrations to dress or act like men. they may require government id such as drivers licenses or passports to identify their sex as male (which it is, genotypically, although not phenotypically). its entirely possible that further rulings may be handed down that in rare edge cases a genetically male but phenotypically female person may be plowed to continue to be named as female on docs. otherwise no effect.
