A staff member, on the basis that she looked and sounded like a man wearing make up.
The changing room had 2 rows of cubicles with flimsy curtains. Women inside heard a man asking to use the changing room, which was quite full, and, when we all looked (out of surprise and nosiness) saw a man, wearing make up, carrying skirts/dresses, demanding to be let in.
The corollary is not lost on me, but as it is trans women making the news and trans men seemingly more quiet on many issues, I have no idea what they think.
Actually that's not quite true. I know that there are an estimated 3 times as many trans women as men in the UK, so we are bound to hear/see more of them.
I also have worked with 2 trans individuals, both trans men, and they were far more accepting of the difficulties the wider society had with the gender fluidity. They were highly active, rallied, petitioned, held and attended regular committees on trans issues, but they weren't as interested in making a public fuss.
Maybe they were wrong, were taking their traditionally female reticence with them on their trans journey. However, they had both had radical surgeries, had fully committed to being male, took voice lessons, were coached to walk, sit, communicate in more male manner.
Maybe, as I said earlier, I have greater reservations when a trans woman is more fully male, is less committed, is earlier in their trans journey. Why is that wrong? I would feel the same about a trans man in the same situation.
