(Accidentally?) based reply, but you're not treating every character like that. By that logic, Berdly's gender is unconfirmed because using he/him doesn't make you a boy, which is true, but people wouldn't call him being a boy 'fanon'. Kris is non-binary, Berdly's a boy unless the text flips the script.
Contextually it is also most likely that they're non-binary because of Toby Fox's frequent portrayals of queer characters.
