I said always but that was a bit of a hyperbole.
From my observations the main reasons people identify as nonbinary are attention/trend/politics, part of coping with rape or sexual abuse, as part of realizing they are trans. The first one comes with no changes to behavior or appearance while the rest do. The first one is also the most common because it costs nothing.

@wowaname @traabot
*rape or other sex related trauma

@matrix @traabot maybe ive been lucky with who i met then lol

@wowaname
Probably. I understand that some people don't always feel super womenly/manly, but if they don't experience dysphoria there isn't a reason to identify as something else.
@traabot

@matrix @traabot thats the thing, many afabs in my life dont really mind being called whatever, but then theres the few people who are actually dysphoric and dont want to identify as anything, and those are the people im thinking about

@matrix @traabot it could be temporary exploration for some people but i dont think its really invalid

and, no, a different hairstyle doesn't qualify as a different appearance

@wowaname @traabot
I also just realized that there's mostlikely a language component to this as many languages don't feature a singular they people can abuse. For example the only way to be nonbinary in the Czech language is to be called "it", which is dehumanizing so not worth it, especially if you are doing it for the first and third reason.
This is just a thought though.

@matrix @traabot grammatical gender is bloat

@matrix @wowaname @traabot Do you also have gendered past tense like Russian? We have gendered plurals in Icelandic

@applejack
Past tense is gendered.
Gendered plurals? Like group of women is addressed differently to a group of men?
@wowaname @traabot

@matrix @wowaname @traabot Ye
They: Þeir, þær, þau
Male, female, neuter

@applejack
Oh yeah, we have that too.

@wowaname @traabot

@matrix @wowaname @traabot It's not in Russian so I wasn't expecting it in Czech, neato
