A gender identity is male, female, nonbinary, and various combinations of male + nonbinary and female + nonbinary (demiboy demigirl etc.) a gender identity is not male + female or male + female + nonbinary (bigender and trigender is not valid gender identity) a gender identity is also not wanting to be an inanimate object, mythical creature, or non-human animals, Xenogenders are an insult to the trans community and what it means to be transgender. If you say your pronouns are catself, dollself, demonself or anything else stupid like that I will not only not use them I will make fun of you for being a sad pathetic piece of shit human who pretends to be trans because he/she finds it so hip and cool, fuck you for appropriating trans experiences.
Let me put it simply then, Gender is based on sex of the brain, some people have a brain that is male, some people have a brain that is female, and some people have brain deformities that render them neither (nonbinary). The people who claim to be Xenogenders or multiple genders are lying because you cannot have brain sex that is a dragon, doll, demon or whatever, and you cannot have brain sex that is both male and female at the same time. They are pretending to be transgender for fun and appropriating our suffering.
