Hmm. I think the questions raised by that quote are interesting -- can we rehabilitate an existing, disadvantaged gender role, or do we need to scrap the system and start over? If the latter really would help, how on earth would one do it?

But I'm also a little uncomfortable with your last paragraph, which seems to imply that living outside the gender binary is a hypothetical option with its merits open to debate, rather than something a lot of people are struggling to do now in the face of constant assumptions that we don't exist.
