Short answer: I'm a realist.
Long answer: I don't like the toony look of furry. It's okay and all when it's in drawings, but brought out in the real world it looks unnatural. Yes, yes, I know that nothing is natural about a furry. This fact has not escaped me, but to have something in reality possesing a toony look is just slightly disturbing to me. Plus I don't like the 'poofy' mascot look that almost all fursuits have. I would want to look like a real creature, be able to talk and interact in suit just as I would out of suit.
I dunno, maybe I just watched too many Jim Henson shows and movies when I was little.
