New one after seeing a stamp on someone's signature.
The general belief that every furry out there is a yiff obsessed pervert annoys me. Seriously. Do you go to a football game and assume the animal mascot is a perv just because they're wearing a costume? No, of course not. Course, CSI didn't help the stigma any (thank you yet again, Hollywood!).
Most of my friends assume the same thing and it irks me to no end.
