I'm pretty sure being a furry fills the requirement for that
It's an interest in anthropomorphic animals, loveual or not.
I thought of becoming a furry because of how fun and creative it looked to create characters and express them with others within the community. I actually made one, but I can't find the motivation to do anything with it, even though I had him as my BLF avatar a few times. I can remember a few non-furries liking him, though.
