'Twitter 'bans women against trans ideology', say feminists'
"Twitter is banning women who "speak out against the dangerous dogma of trans ideology," a feminist group has said.
In a letter to Twitter director Martha Lane Fox, Fair Play for Women says the company is allowing "a concerted attack on women's free speech".'

"Stonewall is calling for a system of gender recognition based on self-identification, and wants to remove the requirement for a medical diagnosis before a transgender person can change their legally recognised gender.
The organisation says changing the law would make life easier for trans people and "barely affect" non-trans people - also known as "cis" people.
In July 2017 then Equalities Minister Justine Greening said the Gender Recognition Act needed to be updated and that a consultation would begin in the autumn.
The Scottish government is currently consulting on gender recognition.
The campaigning group Man Friday argues allowing people to self-identify as a particular gender "removes any gatekeeping to women's identity and protected spaces".
To protest against any change to the law, the group choose Fridays to identify as men and take part in activities such as using male changing rooms.
On Friday a group of women attempted to access the men's only bathing pond in Hampstead Heath as part of a protest against self-identification"
