Why is there a female gender and a male gender.. but no non binary gender? Does not support that?

Honestly i have no idea why. I guess they dont support  it.

Explanation:

usually in apps when they ask for your gender they give you the options female, male, other, or "rather not say"

I doubt they don't add the option "non-binary" because they don't support that, but rather because they don't consider it as an option or because not many people identify as non-binary. Non-binary is apparently not "legally recognized" as an option

They should, add non-binary as an option so that people can identify themselves freely :'

dunno if this answered your question but i hope it did. :)
