What is "gender noncorforming" even supposed to be? While we're at it, how are you supposed to be the opposite that doesn't get mentioned that much, "gender conforming"? And don't come at me with stereotypes to explain it. No one has given me an answer that's not completely stupid so far.
I saw a great line the other day: "Gender is the cultural manifestation of sex." Culture is how certain homogeneous groups do life. How they work, get and eat their food, make art, reproduce. etc. Modern tech and progress has completely deconstructed and rearranged gender conformity/gendered culture. So naturally it is hard to define well nowadays. You have to go back in time to see what they used to be. And do a compare and contrast.
Before the modern age, males and females had separate cultures, separate domains. Gender used to be "vernacular". It was common, capability based labor and social role divisions which supported communal subsistence living. In the deep past, everyone worked their asses off to the limits of their bodies, with consideration paid and allowances made to their sexed bodies and reproductive roles. Because reproducing was risky and really important then. And in that regard, men were expendable. Women for obvious reasons weren't. And getting fresh and healthy genetic material for your family was critical. You could only boink your blood relatives so much before inbreeding depression set in and you got compromised offspring. So yes, women were valued, traded, stolen, "controlled", etc.
Back to divisions of critical labor: Men went hunting. Women foraged. Men lined up and scythed the wheat. Women used hand sickles and gathered and stacked the sheaves. Men went to war and women said "Return with your shield or on it." Women cared for the young, the sick and the dying. Men went down into the mines, into the foundries, the factories, and then up into the skyscrapers.
By the time we hit factory and skyscraper, it was no longer critical that everyone work their asses off to the limits of their sexed bodies to keep the species going. (For some classes, I should add here.) And rigid gendered cultures and domains started to loosen, overlap, and switch places entirely. With the march of modern industrial history, females especially lost their cultures and domains. And their critical reproductive roles. With the post industrial age, they've gotten some new domains, but now they're competing against men instead of working in a complementary fashion alongside and with them.
Gender conformity used to be very practical. It was how you did your part in supporting your clan and community within the limits and uses of your body. Being or behaving feminine or masculine wasn't optional, your femininity or masculinity defined how much (or what) you could do. And you just did it and accepted it because that was just the way things were and trying to push past those limits could get you in big social trouble (for being disruptive or threatening to the community's survival) or in the case of women, get you maimed or killed. Everyone had responsibilities and expectations. Everyone willingly made sacrifices too.
Nowadays there are fewer practical sex based limits imposed on behavior, appearance, jobs, sex, reproduction, etc. Fewer responsibilities and expectations too. Sacrificing anything is for losers. Mainly because we can rely on tech (or the State or the Market) rather than on each other for survival. And to meet our needs or correct our mistakes. And to talk relativistic rings around what used to be absolute truths.
"Gender is the cultural manifestation of sex" and all cultures are being watered down by tech enabled neoliberal globalism and multiculturalism. Sexual ones are not exempt. But the evolutionary drives in our lizard brains remain. And there are certain things that still resonate as right and proper sex based behaviors, etc. So there is still a bit of expectations and responsibility when it comes to gendered culture and domains. For now. But since they're not as critical as they once were, there's squabbling over whether they're completely obsolete or not. Not surprisingly, between generations. And between those who have meaning in their lives and those who do not.
Sorry for the lengthy sperg. I hope that's a more satisfactory answer.
