You can, kind of broadly for ease of understanding, categorize non binary into a few different types.
-
Static identities vs fluid
-
Absence of gender vs mix of gender
-
Trans identifying and cis or ar least non-trans identifying
-
Political or aesthetic versus psychological need
To explain absence and mix are basically what it says on the tin. For some people they want freedom from any cultural or physical gender aspects to the best that can be reasonably achieved or they desire a grab bag from both male and female cultural or physical phenotypes. This doesn't always nessisarily look like or have perfect androgyny as a goal.
Static identities do not change over time. Often these folk either experience a desire for an absence of sex characteristics or see themselves as a simultaneous mix male or female or as a specific other category.
Fluid identities change over time. This could be daily, weekly, monthly or yearly. A fluid person might alternate only between agender (ie no gender) and a binary gender or experience the full spectrum of male to female. Their needs change over time.
Political and Psychological are kind of another slider. For some Non-Binary represents a range of coping mechanisms to deal with gender euphoria or dysphoria. It can be a philosophy that is used to seek a sort of individual path, accepting a middle place ir an extremely nuanced situation where one's birth gender is a problem... But the solution isn't leaping to the full other side of rhe spectrum. For others Non-Binary can be a purely cultural third category. Gender abolitionists exist who find the repressive gender expectations they were subjected to did them harm. They might resent cultural gender rather than having any particular strong feelings about their bodies. Genderfuck or Genderpunk are outgrowths of movements that blend or subvert people's cultural expectations. The establishment of pink and blue boxes is a prison and they want nothing more than to burn it all down.
Transness or "Non-trans Non-Binary" extends from this division. Non-Binary identities fall under the Trans umbrella in the LGBTQIA+ but not every Non-Binary person is comfortable claiming transness as a label. Sometimes it feels to some enbies like they are claiming stolen valor or that they don't intend to physically transition so it doesn't apply (though it's worth mentioning that binary trans people also don't require an intent to physically transition as a gatekeeping item that prevents one from being trans ) others are functionally more cis identifying because their issue is cultural and not physical.
It's a very big tent of different people.
