Problem is, there is a fairly well known disorder where others (such as parents) will embellish/invent medical conditions for those under their care in order to obtain attention/support. As trans issues are being reported as exclusively positive, with any negative attention being censored/scrubbed, it makes it very easy for a parent to "support" their trans child for just this reason, as children generally lack the agency to deny what their parents tell them up until a certain age.
