Just looking at their massive report on bullying in schools.
Sexualised / sexually motivated bullying is not a category - they have physical assault, verbal bullying, cyberbullying. They do not mention sex in the document at all. They do not mention sexual bullying (from a search on the word "sex").
This is in massive, stark contrast to the very large survey the GG did around the experience of girls in school.
This seems like an organisation that is blind to or not interested in the particular issues faced by girls in schools and presumably by women as well.
Not very surprised, seeing the comments from the man who runs it, displaying an utter lack of empathy with girls / women nor any interest in trying to develop any.
