I disagree. I present as female and use female facilities whether it be the bathroom or a changing room. At least where I live both have separate stalls/booths/whatever. I will see no more than I would if I were on the street or, at the most, on a beach. Those who go in to assault, one way or another, already have laws that will deal with them. I just want to make sure my purchases fit/the bladder is empty and be on my way, much like anyone else.
Where would you have me go? The Mens room? LOL. I had to stop that before even going fulltime due to confusion, threats, etc. Why should my safety be of less concern?
Again I pass pretty well so I do not have a lot of these concerns and have not had to deal with things like this (except when trying to use mens facilities before I went FT). I do have to say that in all honesty, I would not care if an unpassable T came in to use the space unless they specifically did things that were not gender congruent. IE. Standing up to pee in the ladies room.
