I must admit...I think it's pretty weird, and I don't really get it.
Scifi fans, I get. Usually there are movies or TV shows or books that generate such fandoms.....and it's the personalities of the characters in those media (or the personalities of the actors, possibly) as well as the storylines of those movies, TV shows and books that tend to generate the interest. Not the lifeless images of the initially rendered characters on a page or computer screen. Scifi fandom centers around storylines and characters - what is underneath those simple rendered images. The look of the character and the costume is very much secondary to the personality of the character and the storyline that character is involved with.
As I understand Furry fandom, it's about the images and the suits. And to me, that feels sort of empty of meaning...and makes me wonder what the draw could be, if it was not some sort of bizarre sexual thing.
It's just the fantasy of it all. Take me for instance: I have a close kinship with animals and nature in general. My faith is a part of that, so the evocation of human sentience in animal form is an outlet of that. I want to draw furry art. I have no real interest in drawing furry art with sexual connotations, I want to draw it in more of a religious/mystic connotation, the idea that we are a part of mother earth, a part of nature. I believe animals have souls. That is a major part of what drives me in that regard.
For example, I love this kind of stuff:
This is anthro art.
That said....I think alot of scifi fans take fandom too far as well. I mean, there is a REASON they made Trekkies, you know? And there is a reason why the fans waiting on line for Star Wars were such an easy target for Triumph the Insult Comic Dog.
I love scifi and Star Trek...but when a person decides he needs to learn Klingon as a second language, it's time to put down the remote and go get some fresh air.
I can understand the sentiment. Too much of anything, even good, can be unhealthy. It's important to balance it out.
