I think you could have been clearer on when you're talking about physical sex and when you're talking about psychological gender. Are you advocating the elimination of psychological Gender Identity, or the elimination of Sexual Dimorphism?
As someone who has already successfully hacked himself to become Agendered, it is my belief that the former is entirely environmentally caused anyway, and a deep cultural change is what would be needed to address it. However, while I would strongly advocate seeking a future in which each and every individual can have exactly the body they want and not be judged for their preference no matter what it is (or at least no more so than people are judged today on the color of their clothing), I do not think making humanity less than it is by taking away one of its features is an acceptable solution to anything.
What does it mean to be agendered? Can you provide a specific example?
I've never respected gender roles; I'm a fairly androgynous (physically and behaviorally) male and I'm attracted to fairly androgynous females... but I don't know how one would go about "dissolving" their hormones and genitalia.
Upon reading Eliezer's possible gender dystopias ([catgirls](http://lesswrong.com/lw/xt/interpersonal_entanglement/), and [verthandi](http://lesswrong.com/lw/xu/failed_utopia_42/) and the other LW comments and posts on the subject of future gender relations, I came to a rather different conclusion than the ones I've seen espoused here. After searching around the internet a bit, I discovered that my ideas tend to fall under the general category of "postgenderism", and I am wondering what my fellow LessWrongians think of it.
This can generally be broken down to the following claims:
EDIT- Due to some really insightful comments;
I replaced men being prone to aggression as a negative, with men being prone to suicide.
I made the verbiage a little more explicit that no one would be *forced* to change, but would seek out the changes that transhumanism would have available.
