The answer in the modern regime is “no, the concept of a woman is a social construction.” All is relativism, except white racism, the only absolute. Say otherwise and face the consequences:

“A birth coach has been ‘ostracised’ by her professional organisation after transgender activists branded as offensive a Facebook post in which she said that only women can have babies. Lynsey McCarthy-Calvert, 45, was forced to stand down as spokesperson for Doula UK and has since resigned altogether from the national organisation for birth coaches. Her exit comes after transgender rights activists triggered an investigation in which Doula UK concluded her message breached its equality and diversity guidelines. They did not expel the mother- of-four, who has been a doula – who provide continuous support during pregnancy – for six years, but threatened to suspend her unless she deleted the post. Mrs McCarthy-Calvert did so, but resigned believing Doula UK had ‘acquiesced’ to demands from a small number of activists and failed to stand up for women’s rights. ‘I am angry and sad,’ she said last night. ‘I was effectively ostracised for saying I am a woman and so are my clients.

‘I have been very disappointed by Doula UK’s response. The leadership are paralysed by not wanting to upset transgender rights activists. They have fallen over themselves to acquiesce to their demands.’ The controversy comes after a series of recent victories for transgender activists. Flora margarine stopped advertising on Mumsnet after the website was accused of being transphobic for hosting a wide range of views on transgender issues. And the makers of Always sanitary towels removed the female ‘Venus’ symbol from packaging after complaints from trans men. The Doula UK row started after Cancer Research UK dropped the word ‘women’ from its smear test campaign, instead saying screening was ‘relevant for everyone aged 25-64 with a cervix’. In response, Mrs McCarthy-Calvert posted a photograph on Facebook of a negligee-clad woman somersaulting underwater, with the wording: ‘I am not a “cervix owner” I am not a “menstruator” I am not a “feeling”. I am not defined by wearing a dress and lipstick. I am a woman: an adult human female.’ Beneath it she wrote: ‘Women birth all the people, make up half the population, but less than a third of the seats in the House of Commons are occupied by us.’ She claimed women were accused of transphobia more than men, arguing men were not ‘subjected to cries of bigotry and transphobia when they say they don’t want to have sex with a woman with a penis’. Most trans-women have not had their male genitalia removed. A Facebook follower accused her of using ‘absolutely disgusting language’, adding: ‘Also, you seem to be forgetting that not only women birth children.’

     We are only a breath away from hate-laws outlawing such speech, and imprisoning people making it. The UK is way down the tracks on this one:

“Judges have been ordered to hand out tough jail terms in a crackdown on transgender and homophobic hate crimes. Offenders found guilty of stirring up hatred on the grounds of sexuality should get at least six months in prison, new sentencing guidelines state. And there should be a six-year jail sentence for those convicted of the worst cases of intolerance against gay or transgender people. The instructions, released yesterday by the judge-led Sentencing Council – the statutory body that recommends punishment levels – mean transgender hate offences will receive harsher sentences than domestic burglaries. It comes after police figures revealed reports of hate crimes soared last year, with transgender hate crimes up 37 per cent on the year before. Mr Justice Julian Goose, of the Council, said the guidelines would help the courts take a ‘consistent approach’ to sentencing the offences, adding: ‘Public order is essential for the safe-functioning of society and the law seeks to protect the public from behaviour which undermines this.’ The instructions, which will come into effect on January 1, follow a series of cases in which police have been accused of launching heavy-handed investigations into transgender hate crime allegations.”
