Official guidance distributed by the organisation, which applies to Girl Guides between the ages of five and 25, tells guide leaders to let "transgender" members share changing rooms, toilets, tents, and cabins with girls while away on excursions.
The move came as the 107-year-old organisation updated advice regarding male guides who "identify" as female, a demographic it was revealed in January is now being admitted to the girls-only organisation.
On its official UK website, Girlguiding UK says that for transgender people, "the use of gendered facilities, such as toilets, can cause anxiety".
Comment: Only trans-anxiety is important. The girls' parents' anxiety? Irrelevant. The anxiety of the girls themselves? Well, that's just downright transphobic, now isn't it.
"Members are entitled to use the facilities of the gender that they self-identify as," adds the organisation, which confirmed when asked by the Mail on Sunday that this includes showers, toilets, and changing rooms.
Earlier this year, Girlguiding Chief Executive Julie Bentley stated that the move to allow male children to join as guides follows rules set out in the Equality Act 2010, which "makes clear organisations providing single-gender services should treat people according to their acquired gender".
"In line with our values of inclusion, we welcome any young person who self-identifies as a girl or young woman," said Bentley, a pro-abortion campaigner who describes Girlguiding as "the ultimate feminist organisation".
Comment: No, it's not. A feminist organization would stand up for the rights of their girls and young women.
The radical changes made to the Girl Guides' single-sex policy in January apply to adults, and declare that it would be against the law for guide leaders to tell parents that their daughters are being supervised on trips by transgender people.
In addition, the guidance states that families should not be told if a "transgender" child joins their group, adding that it is not "best practice" for parents to know if their daughters are sharing facilities with males who "identify" as female while on trips away.
Conservative MP David Davies told the Mail on Sunday: "If transgender girls who are physically male are going to be sharing facilities, it's going to make some girls threatened and uncomfortable and the Guides shouldn't be doing that."
Comment: That should be common sense. The fact that it is not, apparently, should be troubling.
As reported by Breitbart in 2013, Girl Guiding in the UK decided to do away with the oath to God as said by girls at meetings, replacing it instead with an oath to "myself", arguing that continuing the strong Christian roots of the organisation discouraged some from joining.
Comment: Replacing God with "me" - a better self-indictment of modern culture we haven't yet seen.
Last week, Breitbart London reported how campaigners have warned that government plans to let people "self-identify" as the opposite sex without having even to see a doctor will put female prisoners at risk, after a study revealed more than 40 per cent of transgender inmates are sex offenders.
