Earth to Les: Under your preferred rules, your daughters are sharing lockers and bathrooms with trans boys. Some of whom, by the way, are straight. And horny. Want to worry about something? Worry about that.
It's really quite revealing how, in their effort to push their message of hate against trans girls and women, they have to just erase the existence of trans men. It shows just how much of their prejudice is based in ordinary sexism: that female-bodied people are helpless, incapable of aggression, unable to defend ourselves, and must be protected from the penis-wielders.
(Also shows how much they have in common with certain groups of feminists and/or lesbians, who do exactly the same thing: refusing to take trans men's maleness seriously, while barring the door against anyone who's ever owned a penis)
