Oh I am totally sympathetic to those caught up in this, hating their bodies and their perceived role. My worries are not about them at all, except for the small number of women hating activists (and I'm not sure all of them even could be described as transgender except when that category is wide open - there seem to be some very strange people who have been attracted to the 'fight') my concern is the approach of the medical and therapeutic community, and especially with regard to children.
When I was an adolescent I didn't want to be a girl at all. I wanted to be a boy, with all the prospects and none of the fears (as I saw it). The changes associated with puberty frightened me, I didn't want breasts and I certainly didn't want periods (haven't much changed my mind there!). I wore boys style clothes when I could and was very happy to be mistaken for a boy, having been a tomboy when I was younger. But no one said anything about it, it seemed to be accepted one of those things some children go through, and as I grew up I got accustomed to my new body and discovered that plenty of other people fought against the stereotypes. My parents had a strong religious view of us as being special unique individuals created by god which I think probably also helped (and were both accepting of homosexuality which I suspect matters quite a lot too).
Now in theory many of the barriers I worried about have gone, but the stereotypes seem to be so much stronger now that I imagine some people may feel more locked into their persevered prescribed roles and much less able to give them the two fingers. We had a big pride thing at the university I work at and some of the publicity linked to the 'gingerbread person', which starts off it's quick talk about gender with an allusion to Men are from Mars, Women are from Venus, and the website has a whole bunch of people saying how great it is, with I think only one person saying what a load of hooey that whole concept is.
It's not 'feminine' to be caring nor 'butch' to be aggressive etc etc, these are just human characteristics that some of us have more than others, dependent on a huge range of factors of which gender is only one.
