No offence but some younger queer people heard "nonbinary is not a third gender" and interpreted that as "no nonbinary person identifies as a third gender".
And some people heard "nonbinary people are outside of the gender binary" and interpreted that as "no nonbinary person identifies as a binary gender. no nonbinary identifies as both 100% a man AND 100% a woman because that's not outside of the binary". (????)
And some younger nonbinary people seem to have internalised "well I'm nonbinary and I don't feel that way so you're wrong", even though the entire point of being nonbinary is that there's literally infinite ways to experience gender.
What I'm trying to say is, there's an identity entirely built around not fitting into narrow boxes, and yet a hefty chunk of our own community seems hellbent on forcing us into boxes anyway.
