I can't wait for this particular story to descend into the pop culture septic tank.
Unfortunately when this person chose to be associated with what I refer collectively to as "the K-hole" I lost any possible interest I could have had in this story. To me there is nothing interesting or newsworthy about a wealthy, privileged person undergoing gender identity transition and making a public spectacle of it to boot. What is newsworthy is the number of transgender people, particularly of color, suffering from poverty and violence. Laverne Cox (Orange is the New Black) said this quite succinctly the other day.
Orientation is orientation and identity is identity, and each of them is a spectrum, our place on which may or may not shift over time. When I teach about this stuff, I show them as two intersecting lines, with the place that that they meet being different and sometimes fluid for each individual. Although I am oriented principally towards guys, I am growing to resent the term "gay" because it triggers so many assumptions on the part of other people, many of them also gay, about who I am and what I "should" care about. I have not and don't see myself ever being curious about living as a woman, and don't quite understand why many people seem to believe that same-gender attraction brings with it a tendency (or even an obligation) to adopt traits of the opposite gender in one's self.
The reason, as I understand it, that the two are lumped together is because the root cause is the same. Society has had very concrete idea about sexuality and gender roles since (at least) the Victorian era, and at its core is sexism. We have been raised with the idea that to be male is superior to being female. Thus men expect more power and privilege, and become defensive and even combative if women try to assert these things for themselves.
In that world, a man who chooses to present as female (or even exhibit stereotypically female traits like gentleness, demonstrative expressiveness, or highly-visible emotion) is seen as a deviant, because why would you want to give up privilege? And a woman who wants to present as male (or even exhibit male traits like toughness or authority) is frequently seen as either a threat or a joke.
So politically, it makes sense, because, really, who else is going to fight for you? But it has been an uneasy marriage in many quarters, and there are plenty in the trans community who don't see themselves as a part of it. But why, like Jenner, they choose to vote against their own rights is anathema to me.
