That doesn’t make it simpler. You’ve now given them ammunition for their delusion. They can mutilate the body too easily today. Johnny turns his penis into a “vagina” via surgery; he no longer has a penis, now he has a “vagina” so is he a male? They will twist and contort this to support their mentally retarded reasoning.
Doesn’t seem to me almost all those girly boys are not willing to sacrifice their penis in order to prove they really want to be a girl.
