This is some of what they say:
We want to see schools, colleges and higher education establishments hold neutral space for students as they explore their gender, sexual orientation and identity formation. We value supportive environments for students, so they feel neither encouraged nor discouraged to follow certain paths.
We advocate for an evidence-based approach to gender distress, and we would like health care professionals to take the time and care to evaluate the low-evidence base for the current affirmative approach, looking more closely at the harms that medical treatment paths can cause. We recognize the high occurrence of comorbidites such as autism and ADHD among children and young people who are questioning their gender.
