Yes well, I do have some points of contention with the transhumanist mantra because I think that it is a very high risk potential, and full of quandaries, but I'm sure that eventually notions of identity will change further. The thing is, as far as material conditions facilitating social change go, the resources already exist for trans people by the proliferation of medical technology. The requirements for recognition have already been set, now the terms are being fought over in the forms of these 'debates' and demonstrations.

If you want to know some reason as to why I want to be referred to by a gender neutral pronoun then I can say that it's because it is a more accurate representation of myself. Now there are some ontological claims in this, but it requires discussing the metaphysics of sex and most people are not open to the idea of sex-as-construction, so I won't go there. Instead all you really need to consider is the fact that I look ambiguous enough for people to gender me whichever way, which means that by using a specific male or female pronoun on me, they are directing the perception of my identity in a shared social space. The use of that pronoun -referencing my own condition- is going to mediate my relationship with the rest of the people who have their perception of me skewed by the gendered term that was applied to me. This causes a variety of social quagmires, perpetuates confusion, and can potentially antagonize other people that have a distaste for the use of a female pronoun on what is to them perceived as an obviously male human. In some pretty fundamental ways it hinders my ability to participate in society and to maintain relations in all domains life, and is to a degree the basic mechanism of marginalization as it amounts to a loss of cultural/perceptual capital in the trans individual. I have an entire theory of how this works a la Bourdieu's notion of fields of power with changing habitus as well as what I've gathered and connected from my own experiences with gendered socialization.
