This comment on considering yourself "non binary" or not, comes from Connie:
"I know that I am not non-binary, and never have been. I have purposely lived toward either end of the gender spectrum for nearly seventy years, but never felt comfortable anywhere in-between. For those who are wanting to find comfort there, I can only imagine how difficult that might be. Of course, I absolutely know how difficult it has been for me to live as either a man or a woman, but I have always tried to be as unambiguous about it as I could be; people can usually conclude my gender by my presentation (whether they accept it, or not, is a different subject). To be non-binary in one's gender (or genderless) identity, though, can only be made known to others by declaration.
Non-binary people don't necessarily present themselves ambiguously or as androgynous. Some can be easily perceived by the average person as decidedly binary. As difficult as it may sometimes be for a binary trans person to project their true gender identity, non-binary people cannot rely on their presentation for others to see them as they see themselves to be. Mis-gendering must be a constant problem for those who see themselves as neither he/him/his or she/her/hers. They/them/theirs would have to be conveyed in some way other than physical presentation, anyway.
Somewhere between gender binary and gender non-binary, there are those who consider themselves to be bi-gender, or even pan-gender. Others may still be gender questioning. The only thing we can be sure about, then, comes from the adage: If you've met one trans person, you have met one trans person."
Perhaps the difference comes with the younger generation. Several of the ones I have met recently have steered clear of the "transgender" label. But as I said, a label is just a label.
