They have answered that question?
Is being transgender a mental disorder?
A psychological state is considered a mental disorder only if it causes significant distress or disability. Many transgender people do not experience their gender as distressing or disabling, which implies that identifying as transgender does not constitute a mental disorder. For these individuals, the significant problem is finding affordable resources, such as counseling, hormone therapy, medical procedures and the social support necessary to freely express their gender identity and minimize discrimination. Many other obstacles may lead to distress, including a lack of acceptance within society, direct or indirect experiences with discrimination, or assault. These experiences may lead many transgender people to suffer with
anxiety,
depression or related disorders at higher rates than nontransgender persons.
According to the
Diagnostic and Statistical Manual of Mental Disorders (DSM-5), people who experience intense, persistent gender incongruence can be given the diagnosis of "gender dysphoria." Some contend that the diagnosis inappropriately pathologizes gender noncongruence and should be eliminated. Others argue that it is essential to retain the diagnosis to ensure access to care. The
International Classification of Diseases (ICD) is under revision and there may be changes to its current classification of intense persistent gender incongruence as "gender identity disorder."
So, transexuals dont suffer because of their condition? Welp, you better tell the transexuals their distress is all in their head!
Look at my link above. The ICD10 is an INTERNATIONAL classification of disease established by the WHO.
BTW, the APA is a bunch of political horseshit. A few years ago they said if you dont identify as liberal, you are insane.
I have seen somewhere where alot of the people that run that malarkey are homosexuals. They took gayness off the list of disorders in the 70s with no scientific basis. Only 1/4 of doctors in their panel agreed with that assessment. ONE FOURTH. They are activists. Nothing more.
Go and try to cite the APA in a court room

They say transgenders are just as mentally healthy as sane people despite their almost 50% suicide rate

They also label insomnia as a mental disorder but not transexuality? tsk tsk
Check out the ICD10.
