The medical community caves to political pressure. This isn't based on science. This is politics. Anorexia is very similar to Transgender in the way they view themselves.
Why then are Anorexics not told by this same medical community that they should go on diets and confirm the image of themselves as they present it as they do the trans? I will answer this for you.
Because the Anorexics are not political activists with an agenda. There not putting political pressure on the same medical community as the trans are to remove their mental disorder from the books nor being treated by this same medical community with confirmation for the false image of themselves.
