Nothing wrong with having a non-human persona, I'm friends with several furries from college and people online, plus I happen to also have a non-human persona, so far it seems to be the rarest type a robot based one (see my profile image for that). The fun part is those with non-human personas are a very diverse group and we are everywhere, I also have a sneaky feeling that some of the moderators on the forums here are part of the group (Based on profile pics and names used) and some of the devs at Chucklefish are also in the same group (Some of the races and items you find in the game are a good hint).
Can probably safely say Jonesy is definitely a kangaroo furry... If not, I'm probably good as permabanned for that...
