I don't see any reason to hate them. For the most part, they're people who associate with a community. They aren't inherently heinous. Sexualizing/associating with anthropomorphized animals is honestly not as bad as some of the stuff out there. Some of the ones who legitimately think they're an animal are insufferable, but as a whole I think they're fine. People who despise them right off the bat are just being prejudiced, and that's not very cool. It's not like that's all there is too them, either..
