People choosing to express themselves in ways outside the conventions of their gender has been around forever. Tomboys, men with girlish hobbies; it all dates back deep into history.
What’s new is everyone insisting that we make such a big fucking deal about it. That part is a symptom of an excessively self-absorbed society. Rather than letting other people draw their own conclusions and being happy with themselves internally, genderspecials feel the need to impose rigid rules of engagement as a means of generating status.
Also it’s no coincidence that nonbinaries follow the same set of fucking trends in terms of appearance and behavior. There’s theoretically an infinite space of expression between the two poles of “male” and “female” yet curiously they all land somewhere in androgynous dweeb range. That’s more evidence it’s just a style -based subculture that wants to be treated like a protected class for no good reason other than they’re a bunch of whiny babies who have externalized their sense of self worth.
Mods, rockers, greasers, flappers, scene, and queer/enby are just subcultures, made distinct by outside markers and internal values. Yet only one of those threw (and is perpetually throwing) a tantrum when every level of society doesn’t validate them to the most extreme extent. Enbys (and most of the alphabet shit really) are what you get when a subculture can short circuit the social hierarchy by clinging like a remora to a civil rights legacy that, while important, has been blindly fetishized without being adequately tied to the deeper principles behind it.
Civil rights was a triumph of the concept of individual liberty and the idea that you could prosper regardless of who you are and what you look like. Modern LGBT etc. is a bastard version of that where a clique of people with a similar dress code and identical ideas seek to maximize their own personal liberty for the purpose of behaving like egomaniacal, deviant lunatics at the express expense of the rest of the world’s personal liberty to call them out for being assholish weirdos.
It’s purely an in-group, out-group dynamic where the in-group has dyed hair and the out-group deserves to lose their jobs, go to jail, and have their children starved all for just using the wrong words. The high-minded ideals they constantly invoke are as shallow as they are, and they will never, ever stick to them the second they apply to a member of the out-group. Most of the time the very concept doesn’t even fully compute in their brains.
