seriously if you step into any offline queer space for like two seconds you'll be staggered by the actual diversity of nonbinary people. I knew someone in college who was amab and balding and had a moustache and dressed like a dad and used she/her pronouns exclusively. I knew multiple people who you'd assume at first sight were cishet who used he/she/they. there are people you can't sort into amab and afab because it's literally impossible to tell because they've been playing 4D gender chess for 30 years.
like. none of it matters. you can make as many boxes and labels as you want, it's not gonna stop people from just being people.
