I still sit on the fence personally. I do feel we should use the room of our presentation. However in the mid south, there is still alot of people here that don't feel comfy with "us". So i try to go in with my wife or other gg friends. Sometimes with my cd friends if we all have to go. Saturday night we were at a club with multi stall restrooms. And i saw obvious guys going into the womens restroom. So i really didn't want to in there. My friend and i went together and checked for emptiness. Did our business and washed then left.
For me it's a bit nerve racking to use the restroom publicly no matter how i present. But the advise about guys beating up TG and and such in the restroom may be pretty sound. Women most likely will not beat you up physically. I do fear of that in the men's room while presenting. I do worry about it if i am not presenting as well because men are just that way.
The best defense is to not offend usually.
