If I told you that I decided to buy a greyhound instead of a pit bull because I wanted a dog of a gentle temperament, nobody would scream that I'm a dog racist involving--and--but honestly, it's a stereotype.
At any organized pit fight in which two dogs are really going at each other wholeheartedly, one can observe the owner of each dog changing his position at pit-side in order to be in sight of his dog at all times.
