There is an attack on the word woman. The wording originally suggested in this bill isn't a stand-alone exception, it is part of a much larger movement which seeks to establish in law and society that the word woman means anyone who identifies as a woman, not actual biological women.
This matters because, without a word to describe the group of people who share female biology and experiences of the world, how can we organise together to defend our rights as a political group?
This isn't an academic argument, this is about practical, on-the-ground stuff.
Currently, if we talk about women's health, for example, we know we're talking about issues relating to having female biology - pregnancy, miscarriage, menstruation, menopause, PCOS, endometriosis, smear tests, etc etc.
What does "women's health" even mean, if the group women includes people with penises, prostrates, testicles etc? The trans lobby say that doesn't matter as you should pick whatever health condition or aspect of biology is relevant, and talk about that e.g. "people with cervices" or "birthing body". But what if you want to talk about - and advocate for or allocate funds to - supporting women's heath as a whole? If there is no word for woman that means biological women - and if group biological women together in any way that excludes transwomen is seen as transphobic - how can you advocate for women?
Similarly, if there is no word for woman that doesn't include males who identify as women, how can lesbians ever expect to have exclusively lesbian spaces? Well, these days they mostly can't. Lesbian dating apps and pubs (what's left of them) are full of males who say they are in the category of women. Lesbians who try to assert their boundaries and organise women only spaces are called and treated like bigots.
More generally, how can anyone talk about women's rights if the word woman includes males? And if it's considered bigoted or transphobic to have any definition of women that means just biological women?
If there is no word for women allowed that means actual women, we cease to exist as a group of people united by a fundamental shared characteristic (being female) and lose all rights gained on that basis.
This is what the gender ideology lobby are fighting for. They want to dismantle sex as a meaningful category and are angry with women who want to organise or group together as biological women, they see this as bigotry.
That's why this is important. The gender ideologists are totally out of touch with reality, but somehow have got a lot of traction and are trying to change the definition of woman in law.
Children and young people are being taught that it's bigoted for women to organise together and that sex is a social construct, not a biological fact. If we don't fight it, it will be coded into law.
