I've just started reading it in the hope that someone will finally define 'gender identity' in a way that isn't either based on stereotypes or nonsensical. It's not looking likely, though:
From the first section on 'Transgender Identity':
Each of us is at birth assigned a sex (male or female), based on our physical characteristics.
First of all, we're not 'assigned a sex', our sex is observed based on our physical characteristics.
Most people’s gender identity (the gender with which they associate themselves) and gender presentation (how they outwardly show their gender) will not differ from that typically associated with their assigned sex.
What does it mean to associate oneself with a gender? Is that to do with liking the stereotypes for your sex? Gender presentation is also presumably based on stereotypes. I'm unsure why people not wanting to adhere to stereotypes should be the basis for legislation.
Trans people, however, have a gender identity which differs from that of their (assigned) birth sex. Trans identities take a wide diversity of forms.
Is a 'gender identity' which 'differs from' someone's sex viewed as abnormal or unexpected in some way? Is this not just a way of saying we should all adhere to the stereotypes for our sex?
Trans identity can be “non-binary” in character, located at a (fixed or variable) point along a continuum between male and female; or “non-gendered”, i.e. involving identification as neither male nor female.
Why on earth would someone need a 'gender identity' or a 'trans identity' in order not to adhere to stereotypes?
