Literal, actual biology 😁
As for [your] first paragraph, it will be gone in ten years, and seen as a source of shame.*
But biology / science and fact will always remain...
It really doesn't matter what I think / what you think / what anyone sets as law or policy / what the general population thinks - biology, science and fact remain the same - you are born male or female and there is no way to ever change that.
a fug of confusion and mis-direction, laws and policy documents weighing several tonnes, millions spent on diversity officers, people sacked or de-platformed, flags flown and marches made, books written and data-centres filled with tweets - none of it can change biology...
As such there is technically no such thing as trans - you can not transition from man to woman or vice versa - you can operate and take chemicals, you can't ever become the other sex.
Let's stop the pretence - let's acknowledge that there is a set of people who are hurting because they have body dysphoria and help them, help them to value what they are, help to change society to not gender stereotype and put pressure on children and adults, make changes so that the quiet senstive boy is seen to be as much a boy as the sporty physical boy, that the girl who loves science and computers, or climbing trees etc. is as as much a girl as the one dressing up her dolls and painting her nails...
let's go back to a sunny land of truth and sympathy - not run by those who have hidden agendas / sexual perversions / desires to dominate... it is much easier to show compassion for those who have genuine mental health issues and concerns when their landscape is not being overrun by those with a politicised agenda.
A man is a man - a woman is a woman - end of! You can't change sex.
