Miranda Yardley is a transwoman who is standing up for women. Respect. She makes twelve well-thought out points with supportive evidence, that women have been saying over and over only to be met with hostility and attack and accusations of bigotry. This is one:

To accept that sex and gender are not the same thing. Sex is a biological reality based on reproductive potential, and gender is a social system that harms women through stereotyping behaviour, by giving women the negative stereotypes and men those that are positive; gender itself is oppression, not a civil liberty. All transwomen by definition are biologically male, socialised as boys then usually ‘transition’ as adults, although in the present climate it appears to be coming acceptable for children to ‘transition’, which should be examined critically rather than accepted unconditionally. That our underlying biological reality remains fundamentally unchanged is not a value judgement, it is a morally neutral statement of fact, neither good nor bad, it just is and being a woman is not a feeling or an opt-in.
