My understanding of nonbinary is it, in practice, most commonly means "person for whom it is very important that others do not assume they share the stereotypical traits of their sex"
there are some like this, but for me it just means that I don't really fit neatly into either binary gender category when I'm expressing myself authentically
That’s totally fair for you to feel that way and not consider yourself non binary!
Also totally fair for someone with your same experiences to call themselves non binary!
right, but if a label doesn't correspond to something then it's useless! Why do I not call myself nonbinary but other people do? it's because something about us is different, and it's not any of the traits listed where me and them are the same
If we use your experiential definition from the first Tweet, isn't the difference just that it's trivial to you that people assume you have stereotypically feminine traits? If we take a step back, you can apply that to all gender identification more broadly.
