Dr McCloud believes dangerous predators could exploit this confusion to further target women.
“This is going to make matters much, much more dangerous,” she said. “I am now expected to use male spaces.
“I have female anatomy. It isn’t safe for women to use the men’s loos. It is as simple as that.”
Many gender critical campaigners do not accept the views of some trans people that they have the anatomy of their acquired sex. Campaigners including For Women Scotland – the group that brought the case to the Supreme Court – say women felt unsafe with trans women using female facilities.
Dr McCloud continued: “The approach here is really to treat normal people like me, who just happened to change legal sex decades ago, people who’ve served their country, worked in the military, doctors, lawyers, nurses, just ordinary, hard-working, peaceable people, as if we’re a threat to be contained and segregated.”
Maya Forstater, of campaign group Sex Matters, which was part of the case, said: “[Dr] McCloud may wish to undertake this challenge as a personal pursuit, but… any chance of success lies more in the realm of fantasy rather than reality.
“The Supreme Court has just laid out in a clear and unanimous decision precisely how the Equality Act has to be interpreted, and one of the guiding principles of this exercise in statutory interpretation was to ensure that the Equality Act was compatible with the Human Rights Act.”
And Kate Barker, of the campagin group LGB Alliance, said: “The needs and wishes of a tiny number of trans women like Victoria McCloud cannot supersede the rights of 34 million women in the UK who need and deserve the privacy, dignity and safety of single-sex spaces.”
