That's quite an incisive analysis and it brings up a few things I hadn't thought of before.

the establishment of xenogenders is not merely an exercise in fantastical narcissism and attention-seeking but also an activist project in deconstructing the very concept of gender, which makes room for less extreme deconstructions of gender (relevant to the queer approach to transgender issues, for example) easier to accept.

I had never thought of 'xenogender' stuff as an offshoot of 'queer theory' or a deliberate attempt to 'push the needle' towards acceptance of trans bullshit. I always assumed that such cynicism was beyond the thirteen year olds who 'take this project altogether too seriously'.
