Gender is not a spectrum

Even if you concede every point the author makes (which I don't, but I am not up to writing a rebuttal), you can't get away from the fact that a substantial number of people actually do not, biologically, fall neatly into a 'male' or 'female' box.
This TED talk by Alice Dreger 'Is Anatomy Destiny?' gives a decent overview of a few of the biological sex variants that humans exhibit: http://go.ted.com/4qqoBg
It would probably be helpful to cite some studies here, because there's at least one gross physical characteristic the existence of which suggests just such a neat boxing.
Also, the Quigley scale is useful for describing intersex people--it is designed specifically to model characteristics of a subpopulation whose size might be be negligible. Without numbers or studies, I can claim with the same accuracy that the majority of people have either a functioning penis or vagina (though, in the interest of the anatomically minded, a many of the structures are of course related).
I'm merely suggesting that it'd be helpful in these discussions to have some studies backing up our assertions.
Personally, I have no idea what to do about or with physical gender, which seems to be what you're replying to. I apologize if my reply is off topic.
This article mainly seems to deal with the gender identity and attraction layers (attraction only in so far as the many gender definitions).
My concern with the proliferation of gender identities is roughly in line with the article. Feminism and early movements were inclusive and intended to dispel the idea that men and women were mutually exclusive properties. Instead, I believe, they were intended to show that there was a spectrum between men and women that everyone inhabited. So currently I'm on the same page as the article.
But my concern isn't the logical aspect of non-binary (though that is where the article is strongest) so much as the intention. By listing and itemizing identity you've changed the intent. As a 30 something white straight male I can't possibly understand the stigma, so maybe having your own *gender is preferable, but on the whole it feels divisive and weirdly clinical. That seems self-destructive; instead of making whatever you want to be normative you're trying to prove you're different.
I could probably type pages more, but like you I am not up to writing a rebuttal. At the very least I appreciate the reasonable tone of the article and hope the response to it isn't harsh. This really is one of the most important issues of our time and it feels hard to have an earnest discussion about the pros and cons of how to approach the issue.
In the end I think I agree with the conclusion... We shouldn't be categorizing every possible identity or attraction; we should be making it a more normative part of meeting people casually / romantically to have discussion about who they are and who they're attracted to / into. By throwing up divides we're short changing ourselves.
