I do wonder whether we are now seeing, with the huge rise in trans people (mainly MTT), is because of two main reasons.
Firstly when I grew-up in the 60s & 70s, there was much, what I would define as 'structural' sexism around gender roles. Girls did cookery & needlework rather than woodwork & metalwork at school, girls career opportunities centred around nursing, teaching ot the civil service. Women were not expected to have a career after marriage and so forth.
However children were far less forced into gender specific play, a lot of our time was spent away from adults, play dates with children of the same gender were not yet the thing, we just played with other kids (M&F) in our neighbourhood; climbing trees, making dens, playing tennis, skipping, football irrespective of our biological sex. Pink, glittery and blue clothes, toys were just not that prevalent.
For the past 30 years, the reverse has become true. Male & Female 'structural' sexism has (in the main) been abolished. Girls and boys have equal choices in subject and career options. However play and clothing has radically changed. Children are a huge commercial market for both clothing and toys, and designers have responded to this by creating a gender stereotyped market. Adults control and manage play like never before and observe and comment on children's non-gender-conforming play choices. Thus if you are interested in something not of your normalised gender you feel that you are 'different' or thinking like a girl.
Secondly in recent years the media have begun to heavily focus on gender in fashion, beauty and other roles together with the whole trans question. I guess this is sometimes because they are just being tacky and after a good sensationalised story to sell copy. No doubt certain types of readers like to think 'what does he/she think he looks like' and have a good snigger. The media can no longer get away so easily with articles that are fundamentally racist, ageist, sexist, homophobic (yes, I do know this is not always the case) because the majority of their readers are not particularly interested anymore. So they have started to fill their pages with articles about trans individuals. It then becomes topical, fashionable and desirable to some people who are not so comfortable with the restriction of specific gender expression who think to themselves 'maybe I'm trans?' FFS, even I have briefly wondered whether my lack of interest in fashion and make-up together with an aptitude for maths and an interest in technology is because I have a bit more maleness than other women.
I don't want to deny that feeling trans is indeed a very real and sometimes painful issue for many people, but I can't help feeling somewhat skeptical about the scale of the issue.
