Quoteacceptance of being transgendered and actively pursuing to change from one binary to another is different than acceptance of being something that defies rigid categorization.

Judith Butler -- "Bodies That Matter" and others ("Gender Trouble" "Undoing Gender") -- These are heavy wading, like grad school critical theory texts.
Judith Butler, Ph.D., Hannah Arendt Chair at the European Graduate School EGS, attended Bennington College and then Yale University, where she received her B.A., and her Ph.D. in philosophy in 1984. Her first training in philosophy took place at the synagogue in her hometown of Cleveland. She taught at Wesleyan and Johns Hopkins universities before becoming Maxine Elliot Professor in the Departments of Rhetoric and Comparative Literature at the University of California, Berkeley.

Butler views "gender" as "performative" -- That we perform culturally determined gender roles. "Drag" is a parody of those roles and intended to be exaggerated, stereotypical, and part of a "performance" that is mostly about what culture views as being "stereo-typical" cultural expectations about gender roles.
There are two ends on the gender continuum, and a whole lot of space in between the two poles. Butler uses the term "Non-Normative Gender ID" or gender roles -- "Trans" is not about "drag" -- NOT the assumption of a role, but rather an intrinsic and integrated personal ID.
I'm physically male, 67 yrs old and the androgen assault has left me looking like "man in a dress" -- The cis-women locally dress like me pretty much: pants, polar fleece pull over, boots, sandals, or jogging shoes. Lots of "unisex" items.
I opened the closet door as "non-gender normative" -- I have my share of wardrobe items to die for, most of which I look entirely absurd wearing. And so I just "be me" and not worry about "which camp" I owe allegiance. Some days I do more than others.
The whole gender ID thing is way bigger than "which public restroom."
I don't like feeling a need to "chose" one camp or the other. Sure as hell don't want to formulate some sort of alternative history about who I was as I grew up. I'm me . . . always have been. Opening the closet door just provided for me an option about ID and ID continuum, and let me let go of a need to fit into one camp or the other.
"Not hetero-normative" -- Not a complete solution, but seems to help me be more secure about who I am, how I view myself and the world.
Let's be clear here. Dresses don't work for me, but then I know a lot of cis-women who look absurd in a dress.
