Just to be clear, "doing what we have already been doing" does not involve granting CDs the explicit legal right to use the ladies room. As far as I can tell, what they (and in fact I) have been saying is that "getting away with it most of the time" and "not being arrested when/if there's a conflict" (aka the status quo, by and large) is fine for people who do not identify (legally and otherwise) as and live their lives as women.
Being personally okay with a CD in the women's room is very different from saying that men should be guaranteed access to those spaces if they're wearing a dress.
