Hey anon. Thank you for pointing this out. If you (or someone else) could tell me who my definition leaves out and how it could be reworded to include them, that would be awesome. I pretty much thought ‘identifies as nonhuman’ would cover it!
My definition in question:
Alterhuman: A member of the nonhuman/otherworldly community. Anyone who identifies as, or is connected to, a non-human, or as someone or something from or connected to a place other than this earth.
