It is very likely that most people who condemn the breed have not.
This is just one of those things on which people will never agree.
Just as with guns, some people hear only the bad news surrounding them and therefore believe all guns are bad. And both groups would be wring.
It is very likely that most people who condemn the breed have not.
It's more likely that most people have become informed enough, and well acquainted enough with the breed, to exercise extreme caution around them.
I had my first introduction to pit bulls in 1975, when one of them damn near killed my dog. He was so torn up, our vet just barely saved his life. Later, my mom kept two females that were so psychotic, it was dangerous for family to visit her. Even later, I was saved from being mauled by a pit bull by a small chain link fence and quick reaction time.
Along the way, I knew several people who had horrific experiences with the breed, and have since read countless stories about them attacking people and other animals with little or no provocation.
None of this is opinion - it's my own personal experience, which is backed up by statistics on dog bites/attacks.
