Is that true Terry that more girls than boys are transitioning?
Different groups and different types/situations. 'Trans' lumps a lot of groups under one umbrella, and has done so because it serves a good purpose.
Type one: gender dysphoria from a very early age that persists. Those children almost always grow up to be gay whether or not they choose to transition.
Type two: rapid onset dysphoria. Happens mostly in early to mid teens and is massively girls. In previous years, 60-80% of these girls moved from trans to being lesbian as they grew up, however this is the group massively affected by social contagion which probably changes things. No one is asking why massive numbers of teenaged girls don't want to grow up and become women in our society. because it seems bloody obvious to me .
Type three: adults who identify as trans, often having shown no dysphoria through their childhoods, many of whom married and had children. This group is massively adult male dominated, who went through full male adolescence and male socialisation, and many don't experience gender dysphoria, hence the insistence that gender dysphoria isn't part of being trans. (People with gender dysphoria arguing that if you don't have dysphoria and want to identify as the other sex for other reasons aren't really trans are named truscum by the trans lobby.) This group also involve people who would previously have called themselves cross dressers.
Type three are the ones leading the TRA movement. Transmen are nowhere in the trans agenda at all, no one's interested in getting transmen into positions of power which tells you a lot about how the group really feels about women. However type three are the ones pushing for the changes to the GRA for people with type one and type two, never themselves having had the experience of growing up with gender dysphoria, or taking radical medication in a way that is effectively chemical castration. They're also writing the education policies which LAs are swallowing whole (ie segregate out children with learning difficulties and train them in their 'assigned at birth gender' by separate and very stereotypical 'boy' or 'girl' play experiences because they won't apparently develop a sufficient sense of gender themselves. If they don't like it when you don't let them play with the frozen frocks or the lego aged three, you then explain that they are gender fluid and encourage them to find their true gender. I wish I was kidding.)
Most of type three are thought to have autogynephilia (sexual attraction to thinking of themselves as women, dressing as and acting as a woman, being included in validating situations as a woman by other women - 'girl talk', experiencing objectification and cat calling, changing alongside women etc) which is where the 'all women get turned on by themselves when they get dressed' statements come from. This group is almost exclusively straight, so men attracted to women. Worth looking up 'trans widows' as a phrase.
