I'm still sceptical whether a child can 'decide' to be a different sex. I suspect nurture is as influential as nature.
Maybe it's my own childhood that makes me so sceptical, knowing how much I hated to be a girl and expected to do 'girly' things by all, except my Dad. Maybe that's because I was the youngest of 5 girls and my dad had always hankered after a boy and I became the 'boy' who joined in with all the things my dad did, although my Dad did teach me how to make my own clothes, and used to cut me dress making patterns from pictures I saw in trendy magazines. It was cheaper than buying them for me.
Would I have 'decided' to be a boy, given the opportunity? I don't know for sure, but I doubt it. I am happy as I am, and I don't let gender 'expectations' affect my choices. I had motorbikes, fast horses, set up my own business (with support from my husband), and I am definitely not the girly type who spends a fortune on clothes and make up. There are more interesting things to spend money on.
I remember raging in my early married days that I had to get my husbands 'permission' to take out a bank loan, even though I earned more than my husband. I still get annoyed when I think about it. I wouldn't have been angry if the same had applied to married men, ie. they had to get the wife's permission. It was the inequality that annoyed me.
I guess I've always been a bit of a rebel.
I appreciate your frank self-analysis. I'm not sure what you mean by "Would I have 'decided' to be a boy, given the opportunity? I don't know for sure". I have to assume you are talking about the hypothetical opportunity to rub a genie's lamp and "hey presto!" you become a boy and that you are not talking about a Heath Robinson medical conversion where you end up a counterfeit boy.
Nature versus Nurture is crying out for a long-term historical Scandinavian-type trial coupled to multi-variate analysis by DNA, occupation/vocation, single vs mixed schooling, life-style, personality traits, etc etc.
Meanwhile I keep wondering about showbusiness, theatrics and dancing in particular; do these vocational/social-environmental categories attract males with personalities and aspirations which foster a (latent) homosexuality or do these vocational categories nurture such tendencies. Maybe disentangling cause & effect is of little consequence. Maybe it's a bit of both, where nature gives a guy an inclination in that direction and from there on the guy finds a substantial minority that gives him a safety in numbers and a per group to exercise or even discover within him self those tendencies.
Could the critical correlation factor that draws one to showbiz be a self-absorption bordering on narcissism? I ask this because self-absorption among young people has been a growing trend linked to our postwar permissive society, bringing with it a self-indulgent irrational pursuit of self-identity fads, including sex-identity projection. As for the transgender journey from gal to guy, it's just a case of a different menu of identity goals or aspirations, eg sports/athletics, military
I'm becoming out of my depth here, not sure if feminism can morph into female power then into power per se and then into male power and thereupon "changing" into a male.
Also, after I'm looking at the weblink below I'm starting to question the reasonableness of my own prejudices. Could it be that the pursuit of sex ambiguity is a path to sex equality? Why bother coming to terms with differences if one can blur or remove those differences?
