Nonbinary people

genuine question here. are non binary people valid to you guys? as in the 'identity' itself, or whatever. every nonbinary person I've ever met, never actually tried to... idk? transition? pass? not sure if that's even a thing for them, but anyways. most of the ones I've met, were always women who think its quirky and cool to be 'trans' (despite it being an actual medical condition.) and acting as if we share the same experience even tho all they did was wake up one day and decided to use different pronouns lol.

my question is, is there any proven science behind non binary people? do they have dysphoria? and if they do, how does it work? not sure if this is the right subreddit to ask about this, but im sure I'll get slimed for it anywhere else, lol. to me as a transmed it just doesn't make sense how one can think they're neither a woman or a man.

however that sounds, i mean no harm by this post
