The Girl Guides have now confirmed that female children (by which I mean those with XX chromosomes and a vagina) should be banned from Guides if they identify as trans. This includes both those who are identifying as boys and those who are identifying as 'non-binary' (which is a label a lot of young girls are choosing these days to indicate that they don't relate to either the stereotype of a man or the stereotype of a woman.)
Such children will be "discouraged" from joining and, if they are already Guides when they start questioning their gender identity, they will be asked to leave - even if they are happy in Guides, have friends there and could do with some stability at a difficult time of their life.
Meanwhile, young males (by which I mean people with XY chromosomes and penises) are welcome to join guides, go on residential trips and share communal showers and tents with girls just starting to go through the awkward stage of puberty, as long as they identify as being girls.
