That is reprehensible. I don't know what we can do about this? Schools have been told they're not allowed to tell children that people are born in the wrong body, so why on earth should an informal educational charity be allowed to?
The guidance for talking to Rangers (14-18) says:
"Right now, this decision doesn’t change anything for our current young members like you, but it does mean that trans girls who hoped to join Girlguiding in the future won’t be able to, and that feels really sad.
We understand this might feel upsetting or unfair. It’s okay to feel angry, confused, or disappointed, and it’s okay to ask questions. We’re here to listen and talk about how you feel. Even though these rules limit who can join right now, they don’t change what Girlguiding stands for.
Girlguiding cares about fairness, kindness, and inclusion and we know you do too. This decision doesn’t mean we don’t support trans people. We still want to be allies and show kindness, and we’re working on what that looks like moving forward."
Nowhere on that page is it acknowledged that any members may welcome this decision. This is awful.
