I have no idea what I'd do. Honestly, I don't think I'd even want to live in this world anymore. Not because of the furry part (don't think I'm letting you off the hook that's seriously messed up), but because it's a great big middle finger to humanity at large. What's better than a human being? Why, an animal, of course. If you're human, the best you can do is splice in some animal, genetically. Ouch, man. Not only would I have to suck up my disgust of furryism lest I become a sad, bigoted remnant denying the next step in evolution, but I'd have to live with the knowledge that these semi-humans are inherently superior to me in every way. I could get the splicing done myself, of course, but I rather like myself the way I am. Having to decide between being smarter, faster and overall more like I'm trying to become vs. staying human but with no benefits... it would probably kill me.
I think the whole scenario kind of puts the furryism thing into perspective for me... it stems from a distrust of humankind, almost to the point of misanthropy. It's not just an appearance or sexuality thing, it's choosing nature over other people. Don't quote me on this, I'm no researcher or anything, but I'm getting this impression more and more.
By the way OP, great question!
