I think one of the more pernicious aspects of the GC ideology is the assertion that anyone who doesn't identity with their assigned at birth sex must somehow be suffering from mental illness.
It's literally
a) a belief entirely in our head, which
b) causes us to attack our perfectly healthy biology through the use of hormones and surgeries.
In short: it's in the mind, and it has deleterious effects, thus it's a mental illness.
I've yet to see anybody cite or reference the exact part of the DSM5 that clearly shows trans-identification to be a mental illness;
Criteria: Gender Dysphoria in Adolescents and Adults
A marked incongruence between one’s experienced/expressed gender and assigned gender, of at least six months’ duration, as manifested by at least two or more of the following:
- A marked incongruence between one’s experienced/expressed gender and primary and/or secondary sex characteristics (or in young adolescents, the anticipated secondary sex characteristics)
- A strong desire to be rid of one’s primary and/or secondary sex characteristics because of a marked incongruence with one’s experienced/expressed gender (or in young adolescents, a desire to prevent the development of the anticipated secondary sex characteristics)
- A strong desire for the primary and/or secondary sex characteristics of the other gender
- A strong desire to be of the other gender (or some alternative gender different from one’s assigned gender)
- A strong desire to be treated as the other gender (or some alternative gender different from one’s assigned gender)
- A strong conviction that one has the typical feelings and reactions of the other gender (or some alternative gender different from one’s assigned gender)
The condition is associated with clinically significant distress or impairment in social, occupational, or other important areas of functioning.
"Desire", by definition, is exclusively mental. So all those criteria except the first one are purely mental. And the first one only refers to gender incongruence in expression, which isn't a pathological trait, and thus doesn't need medical treatment.
So yes, the DSM-5 definition makes it amply clear that gender dysphoria is purely a mental illness, that the hormones and surgeries are to treat a mental illness.
indeed, the generally accepted mindset among the professionals in the field is that trans-identification is both real and rational.
Real, yes, but rational? What's rational about wanting to hurt oneself through the use of hormones and surgeries? What's rational about saying, "Huh, I can totally see that I'm fe/male, but no, I argue I'm not!" ? Trans-identification is completely irrational. It's entirely in the head, and it's entirely at odds with the reality of one's body. It's a mental illness.
Here's the abstract of the first paper you linked to:
Some people have a gender which is neither male nor female and may identify as both male and female at one time, as different genders at different times, as no gender at all, or dispute the very idea of only two genders. The umbrella terms for such genders are 'genderqueer' or 'non-binary' genders. Such gender identities outside of the binary of female and male are increasingly being recognized in legal, medical and psychological systems and diagnostic classifications in line with the emerging presence and advocacy of these groups of people. Population-based studies show a small percentagebut a sizable proportion in terms of raw numbersof people who identify as non-binary. While such genders have been extant historically and globally, they remain marginalized, and as suchwhile not being disorders or pathological in themselvespeople with such genders remain at risk of victimization and of minority or marginalization stress as a result of discrimination. This paper therefore reviews the limited literature on this field and considers ways in which (mental) health professionals may assist the people with genderqueer and non-binary gender identities and/or expressions they may see in their practice. Treatment options and associated risks are discussed.
So in short: genderqueer or non-binary people exist. They may be at risk of victimisation or discrimination. Here's what mental health professionals can do to help them.
Okay, and? Nobody here denies that some people perceive themselves to be transgender, genderqueer, or non-binary. Nobody denies that such people should be protected from discrimination or victimisation. So what's your point?
