alright, what's the simplest way I can explain this...
Okay, while this really depends on who you ask, Loona might be a furry, but she's still a hellhound. That doesn't automatically make her a straight up dog despite her animal-like features. Zoophilia is depicted as an attraction towards animals. Loona isn't technically an animal, as she is far more civilized than our definition of canines. Another key factor is her human form, which she uses to disguise herself among us as a member of the human race. We're also forgetting that she's a fictional character, which makes this debate even less meaningful. You're not gonna see me go out into public and get thrown into jail for wanting to have intercourse with any sort of dog or cat or a f**king horse of all things.
This is the best way I can describe it, so thank you for your time.
