I don't remember the February survey very well at this point, but kind of wonder if there is some bias in the non-furry data due to where people came from. For example, could there have been an significant number of otherkin that didn't identify as furry affecting the questions about feeling human, or people around furry sites for the art that don't identify as furry but still have some related bias. I also don't remember if it just asked where people heard of the survey from, or if they used something like the http referrer too. If the former, I would worry a tad about the bias from possible people coming from 4chan or other sites and faking stuff (as they suggest at least some portion did come from there). Both potential issues might be partially considered by checking for correlations between how they found out about the survey and other results.
