This policy is unfortunately sadly misguided. Research shows the lack of support inherent in this policy will lead to an increase in suicides among transgender youth. For one example, please see: Suicidality Among Transgender Youth: Elucidating the Role of Interpersonal Risk Factors - PubMed (nih.gov). Among the findings--excerpt from the abstract: "Data indicate that 82% of transgender individuals have considered killing themselves and 40% have attempted suicide, with suicidality highest among transgender youth. Using minority stress theory and the interpersonal theory of suicide, this study aims to better understand suicide risk among transgender youth. The present study examines the influence of intervenable risk factors: interpersonal and environmental microaggressions, internalized self-stigma, and adverse childhood experiences (ACEs), and protective factors: school belonging, family support, and peer support on both lifetime suicide attempts and past 6-month suicidality in a sample of transgender youth (n = 372)."
If removing the safety net of school support (as noted above, this can be a protective factor) means that **even one more child** will die by suicide, then this policy should not be implemented.
Please consider that a child-centered and parent-centered policy should never have the consequence--whether unintended or not--of increasing the number of children who die by suicide--let alone the other negative mental health consequences short of death by suicide.
