In "Material Girls" Kathleen Stock says "The Stonewall Diversity Champions scheme gives organisations access to PR-friendlybranding in exchange for their instigating - to put it frankly - certsin measures of social control. Current members of the scheme include blue-chip companies, political parties, local authorities, government departments such as the Department for Education, schools, most universities, newspapers and broadcasters, police and the armed forces, the Crown Prosecution Service, the Equality and Human Rights Commisiion, and many other major national bodies. Effectively, Stonewall seems to be aiming at the removal from member organisations of any public reference whatsoever to sex that might offend a trans person, by anyone. For instance, as already described, it explicitly advises: " You should allow anyone to access facilities, spaces, and groups which align with theirgender identity." More generally, though, there's a heavy emphasis on controlling language and behaviour even when it comes to issues that have nothing to do with space allocation.
