Bolloxio my reaction after reading the scout guidance was immediately to wonder if Guides were deliberately lied to or misled BUT is was also to realise they lacked the a sufficient basic knowledge / ability / confidence / experience / whatever to ask appropriate questions of what they were told too.
If Guides and Scouts have both been advised by the same organisations how come they came to such different policies?
The single sex stuff is an additional layer in that, but basic safeguarding principles which are relevant to a mixed sex setting were also missed / ignored.
Why?
I do think its important to note this, rather than just pin it on the potential militancy of trans activists. You can not get away from the lack of due diligence on display from Guiding.
For me, even if they did manage to come to a policy that was fair and acceptable to girls, if I had a daughter in the organisation I'd be asking questions.
Girl Guiding has lost a huge amount of reputation and trust amongst those who have direct contact with them and who use their network.
A last minute u-turn after pressure, is poor.
