What is "being trans" Tandora?
Is it being one sex but with a deep and aching wish you were the other sex, maybe like a blind person has a deep and aching wish to see, or a lonely little girl has a deep and aching wish that she had been born as one of the popular kids instead?
Or is it actually being, in an innate mental way, in ways we don't yet understand, the other sex, implying that sex is not in fact a descriptor of the body but of the mind?
Because got to say, take away the emotional manipulation and neither definition actually justifies the demands being made of women in its name.
Neither definition changes the fact that people with female bodies do exist and do face social and physical consequences because of those bodies, and neither a man's deep feeling that he should have had a female body, nor a man's deep feeling that women don't need to have a female body, changes the embodied experiences and needs and self knowledge of the people who actually have a female body one iota.
And regardless of which definition you go for, in fact regardless of any definition you go for that places more weight on a man's idea of himself as a woman than the embodied fact of female existence, outside his own mind he is simply not relevant to who women in the original female sense are and what women in the original female sense need at all.
No definition of woman that is stretched to include male people is more relevant to the needs and experiences and reality of female people than the simple old fashioned sex based definition and there is sinply no way round that.
