Experience Tumblr like never before
Do you ever notice how the majority of nonbinary characters are just straight up not human beings? The majority of our non-binary rep is inhuman, which shows how binary society still views us as a literal societal impossibility despite us being here, real people, on earth with them.
I feel like this feeds into the whole thing of enben being seen as like "eldritch horrors" or "other worldly." Even though it might be claimed to be only in jest, it still displays how we are implicitly seen as a human impossibility because of the pervasiveness of the gender binary in society. It's taught to us as "natural" and how "humans have always functioned" despite our modern bourgeois, patriarchal, white-supremacist gender binary originating as a tool of colonialism. That was very recent in anthropological history. (Also note how capitalism is intertwined with binary supremacy here.)
When you delve into this it's wild. It starts surface level but it reveals the core exorsexism and classism of the capitalist society for one, but how it permeates into jokes ("I can identify as an attack helicopter!" "Nonbinary people are little frogs/eldritch beings!"), representation (most nonbinary representation is of inhuman characters) and our legal status (inexistent, which means no civil rights or legal protection of any kind.)
