The absence of any discussion of the epidemic of gender transitioning among both sexes, but especially girls, is glaring and difficult to justify. Prof. Haidt discusses "gender" numerous times as a qualifier between males and females, without once mentioning the unprecedented increase in girls seeking gender TRANSITION services, first described at the U.K.'s Tavistock gender service, beginning in around 2011 and continuing to the present day. The graph shows the rise: "The total number of referrals for 2018/19 in England alone is 624 boys and 1,740 girls. In less than a decade there has been a 1,460% increase in referrals of boys and a staggering 5,337% increase in girls." https://www.transgendertrend.com/surge-referral-rates-girls-tavistock-continues-rise/ The U.K. is just one country. There is a worldwide epidemic of transgender identification in children and adolescents, but especially girls, abetted by the medical establishment and even the public schools, which now tell first graders that they can be the sex of their choice. The coining of a new term, "ROGD" (Rapid Onset Gender Dysphoria) as the result of a study by Dr. Lisa Littman in 2018, took hold because therapists were seeing the phenomenon all over the world and recognized that a new form of social contagion was afoot. If ever there was a bellwether for the uptick in mental illness in girls, this is it. A 5,337% increase deserves a mention, don't you think?
