I was born female.
I started having periods aged 11.
I started IVF in my late 30s and was diagnosed with gyny cancer.
As a result of the surgery (total hysterectomy) which no doubt saved my life, I have no uterus, cervix or ovaries and am childless but am fortunate to be well. My Gyny cancer was unusually caught at an early stage.
I know these to be uniquely female experiences and as an adult human female, I am a woman.
However, some activists with the Green Party have sought to use 'non-men' as a descriptor.

There has been assertions on Mumsnet and elsewhere to use the descriptor 'non-trans woman'

and not using the descriptor 'cis woman' is deemed by some to be transphobic.
Sometimes women have to say 'No!'
I think words matter
I think sex matters
