How do you code them in if no binary
this joke plays on the concept of binary code, which is the fundamental language computers use to process instructions
binary code consists of combinations of only two digits 0 and 1
in the joke's context "non binary" is a term used to describe individuals who dont exclusively identify as male or female they may identify as both, neither or as a different gender entirely.
the joke is a play on words suggesting a funny paradox: if someone identifies as non binary (meaning they dont adhere to the traditional binary gender system of male and female) then how do you represent them in binary code, which only consists of two options 0 and 1?
the punchline is that you cant represent them in binary code because binary implies a binary gender system, whereas non binary individuals exist outside of that binary framework.
