I stand by both those statements.
You can talk about trans people until the cows come home, you could provide the most compassionate and compelling explanation of what a trans person is, none of it would make even the slightest bit of difference to what a woman is.
Because women still exist, whether or not trans people exist. Female people objectively exist, whether or not we are allowed to have words for those people, and whether or not some female people think they are male or male people think they are female. Objective reality will continue to exist.
How on earth could your lengthy and impassioned explanations about trans people change the reality of what a woman is?
Women exist. This site is full of them. And we have a right to describe and discuss ourselves, irrespective of what a trans person is. I'm not a trans person, trans people are largely irrelevant to my life, and I don't need trans people's permission to describe and discuss myself and women in general, in a way that doesn't take into account trans people's gender identities.
As for gender identities not being of interest to other people in general, well, of course they're not. Why would they be? Isn't it rather narcissistic to think that everyone should have some avid interest in the way you perceive yourself? I don't expect anyone else to care what my favourite colour is, or my favourite band. That kind of information isn't on my passport because it is of no relevance to border control or anyone needing to check my ID. So why should gender identity be recorded?
