As is gender dysphoria, as an aside.
Because of the way the medical system is set up, having a diagnosis is required for treatment. That's the only reason gender dysphoria is in there. If you read the definition of it in the newest DSM, that's fairly clear because recommended treatment is social and medical transition. Until transitioning is treated less like a formal medical process and more like body modification, it's gonna stay that way. The APA and medical organizations have come out explicitly stating being transgender is not a mental illness and there's nothing wrong with that.
