Lizzie Streeter, Chair of LGBT Humanists:
‘We support this on the understanding that safeguards to ensure the genuine intent of applicants for legal reassignment will be in place, and that existing Equality Act protections on the grounds of sex will be maintained. All public authorities need to be aware of these, to prevent laws designed to liberate one set of people inadvertently risking the oppression of another, as has happened in at least one recent case.
‘These protections guarantee, for example, that single-sex services or facilities can continue to be restricted to people of one sex only, if such a restriction is a proportionate means of achieving a legitimate aim.’
Looks like Stonewall, Mermaids etc failed on the re-education here.
