this is so true. nobody has to look like anything.
"how was i supposed to know they were non-binary??" ask them.
"well they don't LOOK enby" they don't have to. besides, weren't you taught as a kid not to judge a book by its cover?
"but they look like a girl!!" THEY CAN DO THAT. they can appear HOWEVER they want, it does not change their gender.
non-binary people don't need to be androgynous. they can look masculine, feminine, both, and everything in-between. they are still non-binary.
