Why do people hate rats so much? I live in England and people here are notoriously sentimental about animals, but they hate rats with what seems like an irrational degree of ferocity. Is it just an unexamined bias or is there a logical reason for it? Am I dysfunctional because I don't experience an immediate innate disgust towards rats and actually find them really sympathetic and cute? I just don't get it, please could someone explain it to my moronic autistic brain?
