Where to begin? Stephen's comments in bold.
Clarification: THE GIRL GUIDES
When I said YES (I was asked to answer yes, or no)
I mean: absolutely it is in the right of the Girl Guides Association (GGA), and their individual leaders to choose to have a single sex (or mixed sex) residential or camping weekend
The Girl Guides Association was renamed The Guide Association some time ago. It's operating name is Girlguiding UK. GGUK already takes girls on mixed residentials and jamborees, sometimes internationally. The issue here isn't the mixed sex nature of the event, it's the mixed sex sleeping and sanitary facilities, which parents are not informed of and girls may feel uncomfortable with but may be too scared to speak up in the current climate.
I do and will support the rights of the GGA to determine what that means in any set of circumstances, but I would advise them that it should be done only in consultation with the parents of the girls attending an event, and the girls themselves. where they are capable of comment i.e. Brownies would probably be too young to make serious comment, but they may well have something to say which should be heard, and may be considered
GGUK is not consulting parents, leaders of girls. Brownies and Rainbows are capable of making comment and should be listened to - as is the ethos of self governance in GG - but they still need adults to advocate for their best interests
It is up to the GGA, in discussion with
• regions, districts and troops, AND
• in consultation with parents,
• and girls in some circumstances,
to determine what single sex means, and if that definition might vary in different circumstances. And if they would prefer instead a mixed sex event.
If you're going to pontificate about GG then at least please do some research. We have districts, divisions and counties and units, not troops.
We don't need to determine what single sex means. It's perfectly clear. Sex is already defined as a protected characteristic in the EA2010. In relation to the protected characteristic of sex a reference to a person who has a particular protected characteristic is a reference to a man or to a woman; a woman is a female of any age; a man is a male of any age.
This matters because GG invokes the part of the EA that allows it to restrict membership to those people who share a protected characteristic - sex, specifically female.
If GG no longer wants to be single sex then it can of course change its charter to become mixed. But GG's own research shows that the membership doesn't want to be mixed sex. Lots of info about this on the website.
If parents and children want mixed sex activities for their children then there are many other options - scouts, cadets, Sj Johns Ambulance, Woodcraft Folk, all spring to mind.
The issue with trans children is particularly difficult because no one wants to add to a young person's distress. But I fail to see how it's fair for a male child to be treated as female when legally they don't have female status, and at the same time females are being managed out of GG because they do not identify as girls or are otherwise gender non conforming.
