you aren't the arbiter of your child's bodily autonomy, you're a custodian to prevent them from self harm, and I understand that you think this qualifies as self harm but when you decide to force your child not to transition you're gambling that the ends will justify the means when they have a right to their bodily autonomy
if you make that call without being educated on both sides and actually taking real factors into account like how if you force your kid to repress they might just kill themselves then you're not fit to care for your child and will lose custody (lol, lmao)
if ROGD was real it'd be a fantastic reason to do this, but it's bullshit invented after the fact by people who have already proven that the ends didn't justify the means
