This poll is pretty skewed towards kemonomimi and it's not hard to see why.
To me it probably is because of all the negative consequences with furries like being called a furfag, general hate by everyone, and just easy trolling.
That or people have just not seen "good" furry. In the same way that you introduce a newcomer to anime by showing them a terrible anime that makes them think all anime is terrible, if a person sees bad furry art (which there is a LOT of), then they'll hate furries in general.
I don't mind furry if it's done well and I like kemonomimi too, but then again, I for one have learned to broaden my tastes. If you asked me if I liked furries a year ago, my response would probably be very similar to the majority of responses on here, yet within the last year I've found myself to like or at least tolerate many other fetishes.
