I've noticed this. Why are non binaries always women?
Almost always, but yeah. I genuine believe it stem from the viewpoint that men are actual complete people while having a very narrow image of what women are and what are supposed to be and look like. Women are supposed to be beautiful, sexy, they have to love boys, gossip, cloths, makeup, but also have to be maternal, caring, sociable, etc. Men however can be whatever they want to be. They are complete people on their own and not people in relation to other people (i.e. mothers, wives, girlfriend), or just pretty things to look at.
The woman body is also so heavily sexualized and objectified, and with the accessibility of porn, cosmetic surgeries, Botox, fillers, which more and more young women use at a very young age, makeup, fake eyelashes, filters and AI, it just gets worse and worse. A few months ago or so, I've got an ad on reddit for a dating site/app, that used an image of a realistic, but also unrealistically beautiful, woman that was obviously done by AI. I was seriously appalled. No woman can compare to this. Men might rationally understand that, but it still creates unrealistic expectations in their minds, even just subconsciously.
It may sounds extreme but take into account that these teenage girls and young women are heavily influenced by media and social media. Social media empathizes the sexualization and objectification of the female body with all the makeup, fake lashes, fillers, cosmetic surgeries and procedures and filters, and creates unrealistic, unattainable beauty standards. The media does that to but it also very strongly perpetuate this idea that the man is a complete person and women are just "other" or a character that is not its own character and is mostly there to serve some narrative or be something for that character (i.e. love interest of the protagonist). Not on purpose, I don't think. Or at least mostly not on purpose. But that's the reality of it. The problem of writing women and women protagonists is well known. Even when women attempt to write them. When I was younger and still invested a lot in fictional worlds, pretty much in all the media I consumed (shows, books, etc.), the main characters were mostly men or boys and they were far more interesting and compelling than the female characters. They have faults and they have good and sometimes honorable or awe inspiring characteristics, they can be tragic and complex, the female characters are usually so lackluster in comparison, incomplete humans. This is a problem for the many young women and teenage girls that are shy, introvert and feel they don't fit, who don't have many friends in real life and the way they perceive the world is mostly through the lens of this media.
Many teenage girls or young woman don't connect with the image of women mentioned above. Female people have values and morals too, as a teen I rejected this image of a woman who only care for her looks, makeup, cloths, shopping and boys that I've seen so much in media and which I perceived as very shallow. I felt different than most other girls because I thought they all love makeup and shopping and relationships and all this shit, and I didn't (it was a very skewed perspective and doesn't actually reflect reality, but teens often have skewed perspectives). But back then, this regressive idea of "gender identity" didn't exist, so I never for a second thought that doesn't make me a woman. Instead, I expended the idea of what a woman is. Not all women love shopping, cloths, makeup and are boy-crazy - fact, I don't and I'm a woman. If you remove the sex from the equation, all you left is the person's perception of what women and men are - and this perception is very influenced by media and social media, especially nowadays and in people who are less sociable and more introverted or shy, etc.
tl;dr society has issues with presenting women as a whole person and with sexualization and objectification of the female body, and
Non binary women have an NLOG mentality
Yeah, pretty much. But I think so many has this mentality because of the above.
