One thing I don't understand when people insist that there is such a thing as a 'gender identity' which is unrelated both to someone's sex and to stereotypes, is why it is called a 'gender identity' and not just an 'identity' or 'personality'?
The word 'gender' (when applied to people, rather than as a linguistic term) is commonly used in two ways: either as a euphemistic synonym for 'sex' or to describe the stereotypes which are applied to people because of their sex. So it is always about sex and it is sometimes about stereotypes.
So surely something which is called a 'gender identity' is also about sex (and possibly about stereotypes). If gender is being used in the first way, to mean 'sex', then surely someone who believes they are the opposite sex (despite the evidence of their own body) is suffering from a mental health condition, because such a belief (that someone is something they are not) is a delusionary belief, and indicates mental ill health.
If gender is being used in the second way, to mean the stereotypes associated with the sexes, then a 'gender identity' cannot be separated from the stereotypes applying to each sex. This would explain why the examples of conversion therapy for trans people which you posted last night were all about male people being persuaded not to wear 'women's' clothes.
There is a third possibility, that a gender identity (which is neither to do with the sexed body nor stereotypes) is a sort of quasi religious belief, similar to a belief in a soul which is separate from the body. In this case it would not have to be related to the body, nor to stereotypes, but it would just be a belief in an internal essence of womanhood or manhood. Is this what you believe it is?[/quote]
Think of it as "sex identity". Outside of GC circles, people tend to use "sex" and "gender" fairly interchangeably. In this case, they are using in a way that is more akin to what you would call "sex".
Trans people are not deluded about their sex characteristics - that's why medical transition exists. But nor are they deluded about their gender identity - their innate sense of their own sex that doesn't fit their other main sex characteristics. You can't change your gender identity and trying to do so to someone is harmful (conversion therapy) so they change their legal and social sex, and change their bodies to match their gender identity as closely as possible.
So it's really quite simple - sex characteristics exist, and gender identity exists. In the vast majority of people both match. In a tiny minority, the body and gender identity develop in opposite directions. No one knows exactly why, but as I mentioned above, a range of biological factors have been identified that are assumed to play a part.
Scientists continue to study the phenomenon and more discoveries are made all the time. For example this ongoing research:
www.abstractsonline.com/pp8/#!/4592/presentation/578abstract
That has found:
"...genetic variants in 20 genes that may play a role in transgender identity. The most promising of these include variants of genes involved in neurologic development and sex hormone pathways."
