Transwomen are not women. They can identify as women all they like and I'll nod politely and use their preferred pronouns, but we're not the same, anymore than I'd be a man just because I declared myself to be one.
‘A woman’ is born with xx chromosomes and is born with a vagina, uterus, ovaries etc. Unless there is a specific medical abnormality that clouds the chromosomal distinction, a woman is an adult female.
If someone is born with XY chromosomes, is born with male sex organs and no female reproductive organs they are male.
Anything else including feelings, dress codes, behaviour or appearance cannot be used to change the biological facts.
