On the contrary - those of us who work with children / adolescents know that social contagion is a verifiable condition that's been openly recognised in the treatment / management of children with eating disorders, self harm and related mental health issues for decades.
Research into the fact that children are influenced by social media / peers into thinking their developing pubertal bodies meant they're really the opposite sex, was opposed from the outset by the powerful adult trans lobby. They were terrified at any challenge to their myth of the trans child - this is vital to enable their disordered beliefs to be accepted by the population.
GIDs was shut down because of the lack of evidence and research - all dominated by captured medics in thrall to transactivists rather than practising ethical medical treatment for children.
Societies are finally recognising the harm that of social media and its influence. Try reading some Jonathan Haidt, https://www.anxiousgeneration.com/book

Transactivists have successfully threatened & intimidated professionals out of researching all the reasons for this explosion in girls thinking they must be boys (ROGD) and finally society has woken up to the impact of their bullying. Hence all the new gender services being located in children's hospitals where ethical medical treatment is baked into practice.
I suspect @Collat that you'll dismiss all this as you have done all the words of women on here. I'm just posting it for any lurkers who are unfamiliar with the evidence of how children (and those who professionally care for them) have been silenced and abused by proponents of this ideology
