"This confusion was a conscious contruction of post modernist theories which postulated that you could revolutionise society through the manipulation of language. That we could be anything we wanted to be through altering the social meaning of words."
This comment shows a profound misunderstanding of what post modernism is which is basically a critique of how narrative is exploited by the powerful …so the opposite of what you are claiming. And in any case, the fact 'trans' is a word that distinguishes females at birth from males doesn't in any way conflate the two.
"An adult male, a man is free ( in our society, anyway) to express all of his potential - within the bounds of social rules of behaviour - as is a woman. We can do this without having to so self consciously role play opposite sex 'performances' - but we are also free to do that should we like ( within certain social constraints)"
The fact that you consider organic personality inclinations/preferences as a 'performance' is more a reflection of your own rigid expectations of conformity rather than any credible analysis of human behaviour. That you seriously believe there's no biological naturally occurring autonomy that drives preferences is quite the tell.
But I suggest that denying the reality of biological sex and the consequences of it is a fool's game. To a large extent we are our bodies; we are our circumstances. We are not all 'free spiritual beings' or 'souls' floating around in a world of dense and restrictive matter looking for a place to call home. We are all born into a certain set of conditions which shape our experience. We didn't 'choose' any of them.
Sex Matters, and it matters to women, especially......which is why we have developed certain protections and safeguards. You cannot change your sex...though as you intimate....our sex does determine and shape our life experiences and choices...no matter how much we long to be transcendent beings with no restriction.
Noone is denying the reality of biological sex. If trans people did they wouldn’t need to go to the extent to change their bodies medically. What you are attempting to do here is conflate this strawman with conflicting rights. Again as mentioned upthread, groups experiencing conflicting rights isn't a licence to deny their existence nor is there an inability to manage them.
