Oh yeah, I am inclined to agree. I would have liked to have seen some trans-for-their-society characters, but such characters are missing from the vast majority of scifi that explores gender, and I think what she was doing was still interesting and worthwhile. But a lot of the characters I've listed weren't intended to be representations of non-binariness, including several of the ones I connected with. They're still interesting to think about through a non-binary lens.
