The reason to OP's question is simple, haters hate on the group for the actions of some group members, which you kind of sign up for when you label yourself as a furry. Of course it annoys me that people have to act like such whiny cunts about something they don't like in the first place, but there's nothing you can do about that. If you can't take the hate received, don't label yourself as a furry. Basically the same applies to groups like bronies.
