Maya Forstater has hit back at trans lobbyists who “bully and harass” activists.
Ms Forstater previously lost her job after saying people cannot change their biological sex.
The Equality and Human Rights Commission (EHRC) said on Monday that trans women can be legally excluded from single-sex services.
Following the announcement, the Sex Matters Executive Director has spoken out about the trauma she and others have suffered while standing up for their beliefs on the subject.

The trans debate grew after swimmer Lia Thomas won a female event

She told GB News: “I lost my job for talking about this on social media and really saying the kinds of things that the Equality and Human Rights Commission have now put in their guidance which were judged at some people at my work to be so contentious that I should lose my job.
“I have been fighting a legal battle for the past three years to show that it was discrimination.
“That’s happening all over the place. Where people are being called transphobes and being bullied and harassed at work, it’s because they’re saying the kind of things that the EHRC are saying, which is that women and girls need to be able to have single-sex services and sports."
Asked if the saga has had a negative effect on her mental health, Ms Forstater said: “It damaged my wellbeing, absolutely.
“The situation we should have is a tolerant society where people can believe different things, wear what they want, call themselves what they want."
She added: “But where sex matters, such as in sport and single-sex services, we have clarity.
“That’s the only way we can treat everyone with respect, because people then know where they’re allowed to go and where they’re not.”
The trans debate intensified last month after swimmer Lia Thomas won a female event in the US.
Thomas became the first transgender woman to win an NCAA swimming title in the process.
