Well, I may not know much about what furries, therians, etc do, but this is what GoogleAI thinks of who they are (in sum) because I think that I may have made a worse explanation lol:
"A furry is someone who enjoys anthropomorphic characters and art, often expressing their interest through fan art, costumes, and conventions. A therian, on the other hand, is someone who identifies as a non-human animal, often due to a deep connection with the animal's traits or abilities. While therians might be furries, the key difference lies in the depth of their identification with a non-human animal, which is a core part of their therian identity...
Here's a more detailed breakdown:
Furries:
Core Identity: Enjoyment of anthropomorphic characters, art, and media featuring animals.
Expression: Often through costumes (fursuits), fan art, and attending conventions.
Animal Connection: May have a strong affinity for particular animal species, but the primary focus is on the fun and creative aspects.
Therians:
Core Identity:
Identification as a non-human animal, a belief that they are partially or completely an animal.
Expression:
Can range from subtle ways of expressing their animal identity to more overt ways like altering their appearance or engaging in animal-related behaviours.
Animal Connection:
The connection with the animal is often a deeply personal and internal belief..."
