It really begs the question, now they've admitted they're mixed sex, about what the benefits of joining GG are compared the the Scouts.
The Scouts are honestly mixed-sex. Don't hide this from parents. Presumably do appropriate and above board safeguarding risk assessments for things like overnight stays. So why not just join the Scouts instead?
I hope this means GG will stop lying - even by omission - about the fact that they're mixed sex and the implications for adults supervising and overnight accommodation. I guess we'll see.
