When I was in highschool I developed a very intense dislike for the popular "emo" trend. I created a rationalization for this. People within the trend only belong to it because they lack any discernible personality, and require that association in order to to feign common ground between other people as to form relationships. That is to say, they embodied something that meant nothing so that they could attract people who did likewise. You see this a lot with pretty much every trend. Those who are scene, hipster, Apple fanatics, and yes: furries.
I made a post about MLP a while back in a Chris thread, saying that brony fandom is pure escapism and that the fictional land of Equestria provided a world for unhappy people to escape to. The same idea applies to furries. People who don't fully feel comfortable with themselves develop these fursonas and to help make themselves seem different. It combines an interest in drawing, animals, and individualism into one thing. Niachu doesn't draw anthromorphic art because she may like animals and she may like drawing, but she doesn't feel the need to embody the traits of a cat or a fox to be different.
With anything like this you see a ton of variation. Not all sexualize their creations, not all want to be unique. Some people like, Walt Disney, will draw anthromorphic creatures simply because they want to. While it's possible that Walt Disney was a furry, I'm pretty sure that his success in life earned him happiness, so he would have no desire to embody himself in one of his drawings. There are a lot of artists that draw furry but don't sexualize it, probably because they're conscious that their creatures are fictional, so they have a hard time relating with them beyond the relationship of artist and creation.
I don't particularly dislike furries, but I do dislike people who make themselves all about one thing. It's people who name themselves "FoxVixen", put some skanky anthro fox girl as their avatar, and then post about their imaginary friend and her drawings whenever possible. However, the same thing applies to every group. I knew someone in another community that was so obsessed with Warhammer 40k he'd post in character, especially when someone else posted furry art. Fun fact, typing in big red letters "PURGE THE HERETICS" does not make you cool and it does not make you any better than the people you do not like.
These obsessive people are mentally ill. So are people like Nick Bate (obsession with anal and a particular person), femnazis (obsession with gender and gender equality), obnoxious religious or areligious people (obsession with supernatural superiority), anyone who has ever used the word "cis" unironically (obsession with gender correctness), and so on. Anything can be healthy in moderation. Liking anal and a girl is fine, wanting gender equality is fine, being studied in religiosity is fine, feeling as if you'd be happier as a different gender is fine, but there's a limit. Once you cross that line and start making everything about yourself centric to your obsession, that's when it stops being a hobby and that's when you start being an annoying fucking cunt.
