As a queer glam rocker in the early 70s, I too had a moment when I wished to be female. But, it passed. It was just that I enjoyed playing with gender and being the subject of intrigue and confusion, fucking with scripted notions of gender.
These days, I find it exhausting and frustrating when folks are so self interested and provincial that they demean and ridicule anyone else who fails to conform to their exact ideas about labels and categories. I’m sorry you’ve had to suffer the backlash from this small-minded attitude.
As a cis-bi man, I know what it is to feel like I don’t belong in the ever-elongating acronym. That experience provides me a measure of perspective on (and empathy for) trans folk who are under attack from all sides.
