Just to pick up on this, while Stonewall and Mermaids etc might not 'go into' schools, their material is certainly available in (some) schools. My daughter and all her pangender mates have made liberal use of the books in the LGBT section of their school library. Is this aimed at removing these materials?
It talks specifically about the RSE curriculum so it shouldn't apply to library books or materials. Give this fucking shower another couple of years though and banning books from schools in the name of free speech wouldn't surprise me. Stonewall don't teach kids directly but do train teachers and provide lesson plans and things, but Annex B of the new guidelines specifically recommends Stonewall lesson plans and resources so presumably the DfE feel they are compliant with the rules. Mermaids seem to think they are compliant as well although have pointed out they don't do much work in schools and don't provide education or training directly to schoolkids.
