Realism
Off-track topic. Bear with me here. You ever see a show or movie in which a man took steps to turn himself into a woman–or already had taken them–in which that person was played by a man? Where the woman was supposed to be serious and believable, that is, not obviously a man in drag.
Because if it’s so realistic that men can do this, why are they so frequently (always, in the ones I’ve seen or can think of off the top of my head–Veronica Mars S1-03, Ally McBeal, Transamerica) played by women?
