As I read & learn more about the cis/trans question, I keep coming back to my original, instinctive position: that this is really about gender strictures on men.
I've yet to see/hear anything that convinces me gender dysphoria is about being the opposite sex - and I'm finding plenty of deep discomfort with one's body, deep desires to behave 'out of gender', and visceral rejections of gendered perceptions & expectations of the self. Vast numbers of women, of course, can identify with this. We campaign against it - at every turn confronting walls of patriarchal disapproval, which tries to silence our genuine fears about its impositions of gender on our sex.
Patriarchy imposes its rigid genders on men, too, and silences their dissent with a slightly different carrot-and-stick system. It privileges conforming men more than conforming women - and punishes non-conforming men more harshly than dissenting women. Our advantage of lesser punishment for greater flexibility may be hard-won through ongoing battles, but we have that privilege in most societies now. In some ways, it's the consolation prize for being a "defective man" (thank you, Ancient Greece!)
I can see that some men, strongly rejecting their gender role, would prefer the lesser punishments of being a non-conforming woman. It's also logical that, having received patriarchal training as a superior male for at least their formative years, they might believe they can perform femininity better than most women: thus avoiding all the punishments, being rewarded instead with the lesser privileges bestowed on gender-conforming women.
Feminism has given us terms to describe this class of problems, and patriarchy has limited their application to oppressed sectors. It's easier (though rarely easy) for women to actualise themselves 'out of gender' and to express this verbally. This is why I've left transmen out of my ruminations, btw: a woman can be an honorary man without hormones & surgery; she needs physical completion mainly for sexual purposes. But the man who feels "a real man" doesn't describe him has little access to the language of war against gender. I don't blame him for assuming that, if he's not a real man, he must be a woman - that's what patriarchy has taught him.
I do blame him if, during his transition, he doesn't learn about this. A lot of transwomen do, to be fair. It's just that patriarchy silences their voices too. We're all being told not to mess with the binary - and that is wrong.
... I've realised this should have been an internal rumination rather than a post! But I've typed it, so here it is if you want it.
