Stonewall and other trans groups frequently misrepresent Britain's Equality Act of 2010, which states clearly that single-sex spaces and facilities are perfectly lawful provided they are a "proportionate means to a legitimate aim." They insist, falsely, that separately stipulated protections against discrimination and harassment for trans-identified people ensure that they can access all spaces intended for the opposite sex. Under such false guidance, Girlguiding UK and Sport England have gone "trans-inclusive," a euphemism used to describe policies that enable males and females to "self-identify" into spaces intended for the opposite sex. Anyone with even the faintest grasp of biological reality will see immediately why such policies impact most heavily on girls and women."
