pondering - agreed.
They have some e learning materials for medical / education professionals:

Module 3 is called "Critical information about medical intervention and frontline support." In this module they are quite specific about the importance of adolescents taking puberty blockers at an early stage :
"The suspension of puberty provides a 'breathing space' for young gender variant people to make considered decisions about their future, without the constant distress of changes to their body. N.b. At puberty, young people sometimes evolve as lesbian, gay or bi-sexual. If for these, or any other reasons, the young people ceases to take hormone blocking interventions, the original puberty will resume"
I'm not a medic, but I don't believe that is scientifically or medically accurate - but it is presented as fact. The whole e learning module pushes the importance of early access to puberty blockers - an indoctrination of professionals into their view.
