Thank you, Devlyn. That has been on my mind as I've watched this discussion.
I also decided I'd like to add my opinions and experiences and emphasize that that's all they are - my own unique perspective - as is the case for anyone else.
For decades, long before I ever considered I might be transgender, I've used women's restrooms. I've found them to be cleaner, more spacious, and better maintained. I only ever entered them if I felt confident they were empty, I always sat on the toilets (in closed stalls), and I never left until the room was empty. I didn't want any other users of the facility to be uncomfortable due to my presence. These were all my choices. Fortunately, I never had an encounter with anyone in dozens of these experiences.
Last month, I was in the Seattle airport and had the pleasure of encountering and using an all-genders public restroom. It was large, had open doors at both ends, maybe 20 closed stalls, and very well lit. People of mixed genders were coming and going. For me, it felt so good and so obvious. I have no doubt there are others who could never bring themselves to use it, and that's fine.
I recently said elsewhere in another discussion that, just as Kinsey showed with sexual behavior, I see now how varied and unique gender identity is and realize that it doesn't lend itself to fitting expectations or distinct categories. And I see no reason why that wouldn't apply to a multitude of human expressions - like eliminating waste from the body.
I can't remember where I first heard it, but I strongly believe that when we say something, no matter what or whom it is about, what we're really telling is something about ourselves. How can it be otherwise? We are the observer, the thinker, the feeler, the opiner. As Tanya pointed out, we all have been conditioned to behave certain ways in certain situations, and we naturally impose those expectations on others. I find it incredibly valuable to learn to recognize when we're doing that and ask ourselves: Where did I get that expectation? Is it reasonable to think that it's shared by everyone? Does it truly serve me?
I also firmly believe that much of our growth as adults comes from unlearning conditioned ways of thinking and behaving so that we can finally see who we've always been beneath those layers of obedience training.
But that's me.
