Speaking as a librarian, I wouldn't get too worked up about this. First put yourself in the frame of mind of a public librarian, especially one who's in charge of the children's area. Anyone who's worked in a public library has horror stories galore about the things some patrons do, anywhere from harassing other patrons, to doing terrible things in the washrooms, to jerking off in the aisles, viewing pornography on the computers, etc. Any of which can result in unusually specific signage. Actually most of the patrons are pretty good people, but when you get a bad one... hoo boy.
Basically what you've got here is a case of a librarian saying, "We don't seem to have a policy in place for people coming in who are dressed in a manner that conceals their identity. With the occasional creep we get in here, we should have a policy in place. Let's work on one." Unfortunately, the mental image she's seized upon to represent that valid concern... are fursuiters, even though none have ever come into the library. Her concerns for patron safety are good, but she's fixed on us as a way to explain the type of identity-concealing costume she doesn't want around. (I assume that if a costumer wanted to parade around and got permission in advance, a lot of librarians would be ok with that. Asking ahead is simply common sense for any kind of fursuiting event if you're going to wander onto people's property, be it private or public.)
