Furry fandom, or whatever you want to call it, is usually defined more by the sexual images.
First, though, I'll hit the non-sexualized images. I don't care if you like them, it's not different than liking any picture.
Sexualized animal pictures is, to me, completely bizarre and borderline deviant. If you're into that, fine, but it's not exactly normal to find other animals arousing just because you throw a pair of breats on them. And, no, comparing it to a Twi'lek or a Klingon doesn't standup. For one thing, Klingons and Twi'leks are not real AND they're played by regular ol' human beings. You're objectifying animals and making them into sex objects.
Now, letme put it another way: WHY? Why would you want to make animals sexually charged? Is it some sort of artistic statment? What's the appeal if it's not sexual?
