Also, biological sex matters for so many reasons- especially for women but for everyone.
Biological sex shapes our lived experience.
Girls grow up facing sexual harassment and uncomfortable comments because of their biological sex.
They are made to feel ashamed of their bodies, to be covered up, to look a certain way, to fit a certain standard, from and extremely young age.
The first time I was sexually harassed, I was eleven.
Girls grow into teenagers who get periods, who grow breasts- who deal with discomfort and embarrassment, and sometimes serious health problems relating to this.
They worry about getting pregnant and how this might affect their life chances and choices. They put artificial hormones into their body, and they make plans for what they would do if they accidentally got pregnant. They worry about safe and easy access to abortion.
They face social pressures to look, be and act a certain way. They face not being taken as seriously as their male peers. They read articles in the press talking about girls doing better in their exams or in uni acceptances- but it's phrased like this shows exams are getting easier or something is going wrong. They're made to feel less than.
They stop doing sport, for a wide variety of reasons. This may have health consequences further down the line.
They grow into young women, who may face sexual discrimination in the work place. They may worry about having their first smear test, or pregnancy, or contraception.
They date, fearfully- afraid of male violence and being blamed for it. They are far, far more likely to be sexually assaulted by a man.
They are judged for their life choices, no matter what they do.
In the society we live in, a huge number of aspects of life are shaped by biological sex. A transwoman's lived experience is totally different to mine- I would never try to speak for them. I do not believe they have the right to speak for me, or to silence me. Biological sex matters.
Mumsnet is a really special site for me as a young woman. It has made me feel it's ok to be a feminist, ok to walk away from a less than perfect relationship, given me all kinds of support and advice about my career. Made me feel safer about standing up to sexual harassment. Made me go and get my first smear test when I was putting it off. Helped me get my pill brand changed when I was suffering side affects. All these things are affected by my biological sex. And having a safe space to discuss them matters so much.
