A brief and basic look into Nonhumanity as an identity.
Plain text for each picture under the cut.
Nonhuman as an identity: To identify as not human either fully or partially. (hate/trolls will be reported and deleted)
Reminder: These are all personal identities and why someone identifies as nonhuman and what term someone decides to use for themself is exclusively their business. In the end it is what makes the most sense to the individual and not up to others. Now, onto some of the communities that are included under the nonhuman identity:
Nonhuman: To identify as not human either fully or partially. Used both as an umbrella term, and a standalone identity. How specific you get with your identity and what terms you use is entirely up to you. Sometimes "nonhuman" is enough.
Otherkin: from the term "otherkind" - an identity which typically encompasses being wholly or partially a nonhuman entity. Usually understood to cover those who identify as mythical creatures and other fantastical things, but these are not the only things otherkin covers. Also encompasses non-creature/being nonhuman identities.
Examples of non-creature/being based identities: Conceptkin: an identity where one identifies as a concept such as the concept of night or fire. Objectkin: and identity where one identifies as an object. Songkin: an identity where one identifies as a song.
Examples of creature/being based identities: Therianthropy: usually shortened to therian - where one identifies AS a nonhuman animal. Some will say that this term refers to only earthen animals, living or extinct, but it has never only encompassed earthly animals. The community's language came from those who identify as werecreatures.
Theriomythic: an alternate identity term for one who identifies in some intrinsic was as a mythical creature, typically refers to those with animalistic characteristics. Paleotherian: an identity term for one who identifies as a now extinct earthly animal, like a dinosaur or mammoth.
Cladotherian or Cladokin: an identity term for one who does not identify as a distinct species, but a broader identity encompassing an entire genus or larger grouping. Cladomythic: an identity term for one who identifies as a group (clade) of animalistic mythical creatures.
Fictionkin: an identity term that covers all things fictional. For those who identify as something fictional like characters, animals, species, objects, etc. These can be from books, shows, video games, etc, but not always! Original fictional characters and such are also possible.
There are many other identities that fall under the nonhuman umbrella which is why it's important to do your own research to figure out if a certain term works for you. All these identities share the trait of being involuntary. You cannot choose to be therian, otherkin, or the other mentioned identities.
While the already mentioned identities are involuntary, there are some identities that fall under being voluntary. Otherlink: an identity where one voluntarily identifies as nonhuman. Copinglink: an identity where one voluntarily identifies as nonhuman to copes with things such as trauma, stress, etc.
A lot of people may also say that it is impossible to become a therian, otherkin, etc. While the identity is involuntary, things like trauma and neurodivergence can cause an individual to take on a nonhuman identity when they had not had one previously.
Most will usually see people explain that these identities are spiritual or psychological, but these are only some of the ways that individuals may experience them. Some other experiences of nonhumanity: Symbolic, Metaphorical, Ancestral, Physical (Yes this is an actual reason for some and they are just as much a part of the community as anyone else. Physical and Ancestral nonhumans are part of the community's history and some of its founders.)
For those looking for more information, and community places, here are some places to check out! Werelist, Nonhuman National Park, Alterhuman Archive, The Chimera's Library. The above are forums and archives of information on the community. Most archived information is thanks to who-is-page, liongoatsnake and frameacloud on tumblr.
While this is a brief look into the nonhuman identity that I could share, I do hope it has been helpful in some way. Remember to be true to yourself, and don't let anyone tell you how to feel. Ignore, report, delete and block the haters! Yeen out~
