I’ve never heard it put that way before, but it’s an interesting observation. A lot of animals are culturally associated with personality traits (e.g. clever foxes, loyal dogs, proud lions) and furries usually choose a species they relate to, so it creates a system where people tend to self-sort into various tribes based on values and personality type. Look at any decently popular species and you’ll likely find that most of the people repping it share a common set of traits.
