The provision of single-sex spaces like women's shelters & changing rooms was placed under threat because @stonewalluk, led then by Ruth Hunt, decided in 2014/15 that the rights of males who 'identify' as women supersede the rights of actual women.

Stonewall lobbies government with huge skill and success. Various key figures (incl Nicky Morgan, Maria Miller & Penny Mordaunt) were persuaded by Hunt that Stonewall's version of trans rights was the next vital equality frontier.

The Conservative government wanted to trailblaze on the next equality issue - and not trail behind, as they've usually done on LGBT issues. So they went full throttle at plans to reform the GRA in line with Stonewall's views: self-ID and removal of single sex provisions from EA.

. @stonewalluk's decision to attack women's rights was the moment this once valuable organisations took a terrible, mistaken turn. Its legacy of important work has been tainted by its arrogant disdain for women who value & need the single-sex protections afforded by the EA.

I support this new campaign by @MForstater to encourage to @trussliz to follow through on her support for single-sex protections. https://a-question-of-consent.net 
It's also important that pressure continues to be put on @stonewalluk to step back from its anti-women policy positions.
