There are many animals that have acquired bad reputations in our minds, and the repercussions that go with them. Truth is, if we don't like you, you're in trouble.
Pigs are stupid and ill-tempered.
Sharks are mindless, man-eating machines that endless prowl the oceans for hapless swimmers and divers. The hyena is cowardly and a filthy eater of carrion. Of course, there are more, in fact a long history of our prejudices towards other life on this planet. Added to this, much of our literature through the ages has sustained, instead of enlightened, ourselves about how life really works. Plato's fifth book of The Republic, over a millennia ago, cast doubt on our ability to trust what appears obvious to us.
