Just a couple of quick points.
I think queer theory has been around for decades but really only got a foot hold through becoming more overt in universities.
And in a sense it was queer theory claiming the right over lesbians and gay men that has been (as much of) a problem as queer gender theory has been for women.
So just as some now to trans the past, they also try to queer the history of lesbian and gay movement.
But overall I think what I was trying to say is that it is only because there has been as slow seep into day to day life of queer theory that we now have an extreme arm of it, trans politics.
Just as for instance those of us who grew up pre new technology are able to use it as a tool. But for those who have grown up with it dominating every part of their life accept it as "natural". But between those of us who were early adopters, there was a period when new technology became more common and useful but didn't dominate or dictate our lives.
So it is possible for those who grew up at a time when we all knew about biological sex, it was easier to see gender as a social contruct imposed on us. Those who have grown up and been taught that sex and gender are the same thing, and kind even be a choice, are obviously more suspectible to the arguements of trans activists.
